These BLITZ Washing Machine Cleaner Tablets worked really well in my washing machine. I used one tablet for a deep cleaning cycle, and afterward the washer drum and gasket looked much cleaner and smelled fresh. I especially like that the tablets are designed to help remove limescale, detergent buildup, residue, and odors from areas that are normally difficult to clean. They’re easy to use and work with both HE front-load and top-load washing machines. The 24-pack is also convenient because it provides a long-term supply for regular washer maintenance. A simple way to keep the washing machine clean, fresh, and well maintained.

I’ve been using these tablets for regular washing machine maintenance, and they’ve worked well for keeping the washer clean and fresh. They were especially helpful with odors, and I noticed the unpleasant smell was gone after cleaning. The tablets are simple to use and convenient to keep on hand for routine maintenance. I wouldn’t rely on them for heavy buildup or a deep cleaning job, but they’ve worked well for regular cleaning and freshening the drum and gasket. The 24-pack is also convenient for ongoing use. Overall, they’ve been a useful option for keeping our washing machine fresh between regular cleanings.

Front-load washers are notorious for trapping moisture, soap scum, and grime behind the drum, which eventually leads to that dreaded sour or musty smell on fresh laundry. I picked up this 24-pack of washing machine cleaner tablets to stay on top of regular maintenance, and it makes a noticeable difference. • Deep Clean & Odour Removal: Dropping a single tablet into an empty tub on a regular cycle effectively breaks down built-in detergent residue and eliminates trapped odours, leaving the drum smelling genuinely fresh. • Pro Tip for Front-Loaders: To ensure no leftover foam or residue stays behind in the door seal or drum grooves, run a quick extra rinse cycle right after the main cleaning run. • Unbeatable Value: With 24 tablets in the box and a recommended maintenance schedule of once a month, a single pack provides a full two years of upkeep. If you want to prevent moldy smells, extend the life of your washer, and keep your clothes smelling clean, this is a hassle-free, cost-effective solution.

I tried the BLITZ Washing Machine Cleaner Tablets because my washer had started developing an unpleasant smell and some visible residue around the drum and gasket. After running a cleaning cycle, the machine smelled noticeably fresher and looked much cleaner. The tablets are very easy to use. I just put one directly into the empty washer drum and ran a hot cycle. I like that they help with detergent residue, hard water buildup and limescale without having to deal with liquid cleaners or powders. The price seemed a little high at first, but with 24 tablets in the package and enough for long-term washing machine maintenance, I think the value is actually pretty good. Overall, a convenient washing machine cleaner and descaler for keeping the drum, gasket and internal parts fresh and clean. I would buy it again.

Cleans top-loaders well! I was a bit skeptical because although the listing says it's suitable, the instructions and pictures only show front loaders. My washing machine doesn't have an agitator, and the drum itself is quite clean, but there's always a small amount of odour (not my clothes thankfully). I keep the lid open for at least 24 hours after every load so it dries, but it's not possible to clean without products like this. I put two tablets in on pre-soak, hot, highest water level (top loads always need more cleaner since it's more water). After this cycle, I could smell the cleaning agents. I did another rinse + spin cycle, and the smell disappeared and the drum looks shinier and the smell I usually notice is gone. Because I have two use two tablets, this $25 pack of tablets will last me half a year if I clean every month. I'm planning on cleaning once very 2 months though, since I live by myself so I don't use my washing machine as much as a normal family.

These washing machine cleaner tablets come in a pack of 24, which is intended to be a year's supply. They're individually wrapped double-sided blocks that couldn't be easier to use. All that's required to use one of these is to drop it in the empty washer and run a hot wash cycle. No spin is required so it doesn't take as long as a regular wash. Once the cycle is done, the block has completely disappeared and the machine is left sparkling clean. I was quite pleased with the results of the cleaning tablet. After it was done, the machine was smell-free and clean inside. It's as simple as it gets!

I make it a habit to clean my washing machine every couple of weeks, even though I don't really have issues with hard water, limescale, or heavy buildup where I live. Because of that, I wasn't expecting any dramatic results, but these cleaning tablets seem to do exactly what they're supposed to do. Using them is straightforward. Just drop a tablet into the machine and run the recommended cleaning cycle. There is no measuring, no liquid to pour, and no mess to deal with. That's something I appreciate because it makes regular maintenance quick and easy. After using these tablets, the inside of the washer smells clean and fresh. The scent is noticeable without being overpowering, which I find works well. The drum and gasket also appear clean after the cycle, and the machine feels fresh and ready for the next load of laundry. I use both cleaning products and routine maintenance to help keep appliances in good shape, and these tablets fit nicely into that routine. Since the pack contains enough tablets for many cleaning cycles, it should last quite a while for anyone who cleans their washer on a regular schedule. Overall, this is a simple and convenient product that appears to work well. Even without major limescale issues to deal with, it helps keep the washing machine clean and leaves behind a pleasant smell. For anyone looking for an easy maintenance product for their washer, this is a solid option.

Working amazing !!! Lowkey a bit shocked because I’ve used washer cleaning tablets before & they have never worked as good as these ones

My apartment came with brand new appliances, so I'm actually taking better care of them than I ever did with my old ones. 😂 I got these as part of the regular maintenance routine rather than because I have an old washer with a buildup or odor problem. The 24-pack gives me plenty to keep up with regular cleaning and maintenance throughout the year. For a brand new machine, I'd rather keep it maintained from the start than wait until there's a problem that needs fixing.

These washing machine cleaner tablets are very convenient and easy to use. They make regular cleaning and descaling simple and help remove buildup and unpleasant odors from the washer. I like that they’re suitable for both front-load and top-load machines, and the 24-tablet pack provides a full year of regular cleaning. Overall, a very useful product for keeping the washing machine fresh and clean, and I would definitely buy it again.

These tablets completely refreshed my washing machine. They got rid of that musty smell and cleaned out all the residue around the drum and rubber seal. Simple to use, super effective, and the 24-pack is an amazing value!

These washing machine cleaner tablets are an easy and effective way to keep a washer clean and smelling fresh. The tablets dissolve well during the cleaning cycle and help remove buildup, residue, and lingering odors from the drum and gasket. After using one, the inside of the machine felt noticeably cleaner and fresher. I like that they're compatible with both HE front load and top load washers, making them a versatile choice for different machines. Having a 24-pack is also a great value since it provides a full year's supply when used as recommended. It's convenient not having to measure liquids or deal with messy cleaners—just drop in a tablet and run the cleaning cycle. I gave them 4 stars because heavily soiled machines may require more than one treatment to remove long-standing buildup, and it's important to follow the cleaning instructions for the best results. Overall, these tablets are a simple, low maintenance way to help keep a washing machine clean, reduce odors, and support regular appliance maintenance.

I usuallly put in vinegar Then run a cycle and usually cleans the smell of the washing machine. This tablet seems to do the same, it has a slight 'clean' scent. Visibly, the stainless steel interior seems the same, no difference. I can't say it works better, but I do notice that stains also are cleaned off the steel tub.

With two big dogs in the house, my front-load washer gets a workout. Between their blankets, beds and everything else that ends up covered in fur, I always feel like a regular wash cycle isn’t enough to keep the machine fresh. That’s why I wanted to try these cleaning tablets. The directions are simple. You place one tablet directly into the empty drum and run a hot cleaning cycle, or a regular hot wash if your machine doesn’t have a cleaning program. When the cycle is finished, I run a quick rinse and spin just to make sure there isn’t any residue left behind. The tablet dissolves completely, and there is no strong chemical smell during the process. After the cleaning cycle, the musty smell that sometimes lingers around the rubber gasket is gone, and the inside of the drum looks brighter and cleaner. For regular maintenance, the instructions recommend cleaning the washer once a month, or twice a month for the best results. Since the box includes 24 tablets and you only use one each time, there’s enough for a full year if you follow the twice-monthly schedule. With as much laundry as my washer handles every week, especially dog bedding, I like having these on hand to give the machine a proper clean every month.

I used the BLITZ Mold Stain Remover Gel on stained bathroom grout and silicone caulking, and the results were impressive. The gel helped remove the dark mold stains and discoloration and left the treated areas looking much cleaner and refreshed. I really like the thick no-drip formula because it stays on the grout lines and caulking instead of running down the surface. It’s also easy to apply precisely to problem areas around the shower, bathtub, tiles, and washing machine gasket. A very convenient mold stain remover for bathroom and kitchen surfaces, especially grout, silicone caulk, seals, and other areas where stubborn stains and residue can build up.

This cleaning gel actually works well for cleaning out dirty grout lines and molding caulking. After applying it and leaving it for six hours, there was a noticeable difference in the grout. It does the job without requiring a bunch of tedious scrubbing. The formula has a distinct bleach smell to it. You do not notice it right when you first put it down, but after about 30 or 40 minutes, the scent starts to pick up, so you probably want to leave the room while it sits. You can clearly see the grey line where I tested it and how it contrasts from the black one. Where this thing really shines is on bathroom caulking, which is always prone to trapping mold. It manages to penetrate the surface to clean out the discoloration. My downstairs bathroom has a tile shower floor that gets grime ground into the grout lines over time, unlike an upstairs acrylic tub that is easier to wipe down. This gel took the stains right out. It is on the pricier side, but it saves you the massive hassle of having to strip out and recaulk a shower every couple of years. It cleaned up old lines that were present when I first moved into the house, making it a worthwhile trade-off for the time saved.

I have been looking for a reliable way to clean the stubborn discoloration in my guest bathroom and this gel absolutely delivered. The thick consistency is incredibly helpful because it stays exactly where you squeeze it. When applying it to the vertical tile walls in the shower, it simply clings to the grout lines instead of sliding straight down to the floor. Being completely unscented is another wonderful feature since so many heavy duty bathroom cleaners have an overpowering chemical smell that lingers for hours. Beyond just the shower walls, it worked wonders on the rubber gasket inside my front load washing machine. That area always seems to trap moisture and dark residue, but leaving a thick layer of this formula on the rubber for a short time made wiping it away completely effortless. It even brightened up the silicone caulking around my kitchen sink that had started to look dull over the years. The compact bottle is easy to grip and allows for very precise application right exactly where you need it most. The overall results are genuinely impressive for such a simple cleaning process. It saves so much time and physical energy that I normally spend scrubbing with a stiff brush. If you have older tile seams or appliance seals that need a deep refresh, this targeted formula is a fantastic addition to your household supply closet.

Summary: This gel is the kind of cleaner I keep for bathroom grout and stubborn sealant lines, because it stays where you put it. I used it on tile grout and the discolored caulk area by the tub, and it noticeably lifted grime without turning the whole floor into a slippery chemical mess. It’s not magic on badly neglected buildup, but it definitely beats smearing a spray cleaner around. Pros: • Stays put, so it’s less messy than sprays • Works well on grout and caulking discoloration • Easy to apply precisely in thin lines Potential Cons: • Needs dwell time, so plan a little waiting • Tough stains may require a second round and some scrubbing

I gave this cleaner a thorough workout on both grout and bathroom caulking. On the grout, it definitely made a noticeable difference. The gel consistency is nice because it stays where you apply it instead of running everywhere, giving it time to work on the surface. That said, I have to be honest—I achieved very similar results with my homemade mixture of baking soda, hydrogen peroxide, and a little dish soap, which I've been using for years. While this product works, I didn't find it cleaned my grout noticeably better than that inexpensive DIY solution. I also tried it on some discoloured caulking, but it didn't really restore it the way I had hoped. In the end, and I figured this would be the case, I removed the old caulking, cleaned the area with this product before reapplying fresh caulk, and it worked well as part of that process. I just wouldn't expect it to magically whiten heavily stained or aged caulking. Overall, this is a decent product and the no-drip gel formula is easy to work with. My biggest hesitation is the price, despite coming in a very generous container. Considering you can achieve nearly the same results with common household ingredients for a fraction of the cost, I find it a bit difficult to justify. It's a good cleaner, but make sure you weigh the convenience against the cost before purchasing.

This Seal & Grout Cleaning Gel has been working well for cleaning the dirty grout between the tiles in my bathroom. The no-drip formula stays in place on vertical grout lines and caulking, which makes it especially useful for areas where regular spray cleaners tend to run off too quickly. The gel consistency makes it easy to apply exactly where I need it. It clings well to the surface and starts working on residue and discoloration fairly quickly. I found it spreads smoothly with a small brush or even a gloved finger, so it’s easy to cover smaller problem areas without making a mess. One thing to keep in mind is that it works best when given enough dwell time. It’s not really a fast “wipe and go” cleaner, but letting the gel sit gives it more time to work on stubborn buildup. After letting it sit and then cleaning the area, the grout looked noticeably brighter, and the seals looked cleaner and refreshed. For very old or deeply stained grout, it may take more than one application to get the results you want.

The thick gel formula is what makes this cleaner particularly handy. It stays where you apply it instead of immediately running down vertical surfaces, so it's much easier to target grout lines, caulking and seals. It can also be used in quite a few places around the house, including showers, sinks, tubs, tiles and front-load washer seals. Application is simple—shake the bottle, apply enough gel to cover the area and wipe it clean afterward, repeating if necessary. I also like the precision aspect since you can concentrate the cleaner on the problem area rather than covering everything around it. The 8 oz bottle is compact enough to store easily without taking up much room with the rest of the cleaning supplies.

This cleaning gel is very easy to use and the precision gel makes it simple to apply exactly where it’s needed. I like that it stays in place instead of running everywhere, which makes cleaning around tile seals, grout, and caulking much more convenient. It’s a handy product to have for regular bathroom and kitchen cleaning. Overall, I’m happy with the quality and would definitely consider buying it again.

This gel completely cleaned the pink, slimy mess off my bathroom silicone that used to always come back. The thick gel doesn't drip, so it stays right on the spot without running down. It wiped away all the ugly dark stains and discoloration on the seals and tiles, leaving everything super clean. Very easy to use!
Reza -
Why the Gel Formula Matters: Standard liquid cleaners just run down vertical surfaces before they have time to actually work. Because this is a gel, it clings to the surface and stays put exactly where you apply it. Where It Works Best: Really useful in showers ... especially along caulking lines (or grout if you have tile), and slightly vertical surfaces where normal liquids roll right off. I think with a washer it is easier to just wipe it off ... this is better for porous surfaces that need something to sit on them for a while The Verdict: Simple, practical cleaner that solves the dripping problem when dealing with bathroom seals and caulking.

This BLITZ cleaning gel is a convenient product for handling those small but difficult-to-clean areas around the home. I used it on grout lines, bathroom seals, and other narrow areas where regular sprays and wipes are not always easy to apply. The gel texture is the feature I appreciate most. It stays where it is applied instead of quickly running down vertical surfaces, which makes it easier to focus the cleaning action on specific spots. The precision application also helps avoid wasting product on areas that do not need treatment. The bottle size is compact and easy to store, and the unscented formula is a nice choice for those who prefer cleaning products without a strong fragrance. It is also versatile enough to use in different areas, including bathroom grout and appliance seals. For best results, I found that giving the product enough contact time and wiping the area thoroughly afterward is important. Heavily affected areas may need additional attention depending on the condition of the surface. Overall, this is a useful specialty cleaner that makes detailed cleaning jobs more manageable. The no-drip gel design and targeted application make it a practical addition to a regular home cleaning routine.

Notice, use gloves and good ventilation. We used this gel for our washing machine, which is a front entry one which is common for the lower part of the drum to eventually get mold and nasty bacterial growth. The reason is simple, water pools into the small nooks and crannies. I applied the gel liberally around the gasket, and the silicon seal where dark 'growth' can be seen. Ensure the area is dry and mostly clean (no hair, lint, etc.). Make sure to shake a lot, its a bit runny if not shook, I don't know if this effects the strength or not. I left it overnight, and returned in the afternoon, about 11 hours. And using a wringed out towel in warm water, I wiped it down, it hardened into small little chunks, which is very interesting. I also read the ingredients, bleach and lye, two strong and effective ingredients against mold. Overall, works as expected but be prepared to be very generous with the applicaiton, one bottle might not last that long.

I used this on the grout in my shower and it stuck to the vertical surfaces without running or dripping; it's easier than using a bleach-soaked paper towel on horizontal tub caulking. The gel formula works well on seals and caulking, and it helped lift discoloration with minimal scrubbing. It's easy to apply and the bottle will last for a few bathrooms. Pros: The gel stays where you put it, which makes it easier to clean tight spots and vertical surfaces. It works on different surfaces around the house, so you don't need a bunch of different cleaners. Cons: It takes a bit of time to see results, so you might need to let it sit for a while before wiping. This is a good choice for anyone who wants a cleaner for grout, seals, and caulking that works and won't drip and is easy to use.
