CleenU product solution
Washing Machine Cleaner Tablets
Active oxygen · One a month · Private label
Musty laundry or black spots on the gasket? Drop one tablet in the empty drum and run the tub-clean or hottest cycle once a month, and the buildup drains away. Individually foil-wrapped, factory-direct private label.
- The space between a washer's inner and outer tub stays damp and dark. Undissolved detergent, body oil, and lint stick to the outer tub wall and feed mildew, which grows into black spots. That's where musty laundry and a spotted gasket come from. Each tablet fizzes in water, sodium percarbonate releases active oxygen, and washing soda and TAED help loosen the film in hot water so it drains away.
- Liquids need measuring and can spill; a tablet is one dose that goes straight into the drum. Individual foil wraps keep each tablet dry until use and won't leak in shipping. A once-a-month rhythm is easy to remember, and it gives brands a natural subscription reorder.

Before & after
Before and after (illustration)
Before: a gray-brown film on the outer tub, black mildew dots in the gasket folds, and towels that come out musty. After: one empty cycle flushes out dark flakes, a rinse cycle clears them, the gasket wipes cleaner, and the towels smell noticeably fresher.
- Before: drum film and gasket mildew dots
- During: dark flakes flushed out
- After: noticeably fresher laundry
How it works
How drum buildup gets lifted
Buildup on the outer tub is a mix of detergent residue, body oil, lint, and mildew. Sodium percarbonate releases hydrogen peroxide in water, and TAED activates it to release active oxygen at 104–140°F, oxidizing organic grime and mildew stains. Washing soda raises alkalinity to saponify oils, and surfactants keep loosened flakes suspended so they drain away.
- One tablet in the empty drum
- Fizzes and releases oxygen
- Oxidizes organic buildup
- Run a hot cycle
- Rinse cycle afterward
Usage guidance
Use guidance
- With the washer empty, drop one tablet into the drum (not the detergent drawer).
- Run the tub-clean cycle or the hottest normal cycle.
- Run a rinse cycle, wipe the gasket, and clean the filter. Repeat monthly.

Where Washing Machine Cleaner Tablets stands out
The smell comes from a tub you never see
The space between a washer's inner and outer tub stays damp and dark. Undissolved detergent, body oil, and lint stick to the outer tub wall and feed mildew, which grows into black spots. That's where musty laundry and a spotted gasket come from. Each tablet fizzes in water, sodium percarbonate releases active oxygen, and washing soda and TAED help loosen the film in hot water so it drains away.
Tablets make maintenance simple
Liquids need measuring and can spill; a tablet is one dose that goes straight into the drum. Individual foil wraps keep each tablet dry until use and won't leak in shipping. A once-a-month rhythm is easy to remember, and it gives brands a natural subscription reorder.

Why choose CleenU for Washing Machine Cleaner Tablets?
From product positioning and samples to packaging and repeat supply, CleenU supports OEM/ODM projects built around Washing Machine Cleaner Tablets.
Tablet weight matched to washers
Front-load and top-load machines use different water volumes, so we balance tablet weight, fizz speed, and foam for your target machines.
Moisture-proof packaging know-how
Percarbonate hates humidity; individual foil wraps or desiccant tubs keep tablets effective on arrival.
Sample testing that means something
We plan sample evaluation around washers your customers have used for at least a year: dissolve speed, foam, buildup removed, and odor afterward.
Labels and documents ready
Bilingual label copy, SDS/MSDS, TDS, and batch COAs, with warnings and directions prepared for your target market.
Consistent reorders
Every batch is retained and issued a COA, so reorders match on color, scent, and feel.

Product, use, and procurement
Why does my washing machine smell?
The space between the tubs stays damp and dark, and leftover detergent, body oil, and lint on the walls feed mold. The smell comes from that film, so it goes away once the tablet lifts it and it drains out.
Tablets or liquid washer cleaner: what's the difference?
The chemistry is similar; the format is different. Tablets are pre-measured, spill-free, and easy to store and ship. Liquids suit people who want to adjust the dose. Ecommerce buyers lean toward tablets.
How often should I use them?
Once a month. If you wash baby clothes or gym gear often, or live somewhere humid, every two to three weeks.
What should we decide first for private-label washer tablets?
Three things: tablet weight and count (a 12-count, once-a-month box is the most common), scented or unscented, and individual foil wraps versus a tub. Individual wraps hold up better against moisture.
How do samples and minimum orders work?
Free samples are usually ready in 3–5 days. For tablets, MOQ and lead time depend on tablet weight and packaging, and we confirm both once the spec is set.
Do washing machine cleaner tablets actually work?
Yes, on the buildup you can't see: detergent residue, body oils, and mold film on the outer side of the drum. The black flakes that come out after the cycle are that buildup being lifted off. They won't fix a moldy door gasket, a clogged pump filter, or worn parts, so wipe and clean those separately. Monthly use keeps results consistent.
What's in washing machine cleaner tablets?
CleenU tablets use an oxygen-based system built around sodium percarbonate. In water, it releases active oxygen that loosens residue and mold film on the drum, which is why the tablets fizz. Because it's oxygen-based, keep it away from chlorine bleach and never run it with clothes inside, since it can fade fabrics.
Product usage questions
Where do I put the tablet?
Right in the drum, not in the detergent drawer. In the drawer it dissolves too slowly to reach the tub walls.
Can I run it with clothes inside?
No. Run it empty. The active oxygen can fade fabrics, and clothes block the tub walls.
Black flakes came out after the cycle. Is that normal?
Yes. That's the buildup and mold coming off the tub. Run one more rinse cycle, then wipe the gasket and clean the filter.
Can I use it with bleach?
No. Chlorine bleach and sodium percarbonate cancel each other out and can create harsh fumes. Use them in separate cycles.
How do I keep mold from coming back?
Leave the door and detergent drawer open after each wash, take wet laundry out promptly, don't overdose detergent, and run a tablet once a month.
Does it work in front-loaders and top-loaders?
Yes. Drop it in the drum of either and run the tub-clean cycle per your manual.
Will it clear black mold in the door gasket?
The tablet treats the drum and plumbing; wipe the gasket folds separately, and replace gaskets with deep-set mold.
How do I use a washing machine cleaner tablet, step by step?
One tablet, empty drum, cleaning cycle. Drop the tablet straight into the drum, not the detergent drawer, and run your washer's tub-clean cycle or its hottest, longest setting. When it finishes, run a plain rinse cycle, then wipe the door seal and clean the pump filter. Check your washer's manual for the cycle name.
OEM/ODM customization questions
What can be customized?
All of it: tablet weight and count, formula direction, scent, individual foil wraps or a tub, carton design and language, and ecommerce bundles with a gasket cleaner.
Can we test samples first?
Yes, we ship samples first. Run them in front-load and top-load washers that are at least a year old and smell musty, and record dissolve speed, foam, how much buildup comes out, and odor afterward. That tells you more than a before-and-after photo.
Which documents can you provide?
We provide SDS/MSDS, a TDS, and batch COAs, plus bilingual label content for your target market. We send them per project when you inquire.
Launching your own washer cleaner tablets?
Send us your market, tablet count, scent, and estimated volume. We'll work through tablet spec, carton copy, and directions with you.
