Washing Machine Cleaner · 12 XL tablets
- Tackles odor at the source
- Strips hidden buildup
- Months of cleaning cycles per pack
Your washer cleans everything except itself. Each 40-gram tablet dissolves slowly through a full hot cycle, breaking down the detergent scum and hidden buildup that make a machine smell musty and run worse than it should. Drop one tablet in the empty drum, run the hottest cycle, wipe the gasket. That's the whole job.
Works in any machine that washes clothes: front load, top load, HE, twenty years old or brand new. Unscented, septic safe, and gentle on seals and hoses. Twelve XL tablets per box, a full year of monthly cleanings. About $2 per clean.
Highlights
How to use
Empty the washer and drop one tablet into the drum. Run the clean washer cycle if your machine has one, or a normal cycle with hot water. Wipe away any residue when it finishes. Repeat monthly.

Why not just vinegar and baking soda?
The classic combo froths in the sink but does very little inside a sealed drum. Vinegar is a weak acid that loosens light scale and leaves the detergent gunk and biofilm behind, and run it often enough and that acid can wear on the rubber door seal and hoses over time, the parts that are expensive to replace. Bleach just masks the smell for a wash or two without touching what's causing it. Renuv dissolves the buildup in the drum, pump, and gasket in one cycle and rinses clean, no scrubbing and nothing eating at your seals.

One tablet. One cycle. A different machine.

Everything people ask before buying
Will this work on my washer?
Front load, top load, and HE machines, across every major brand: LG, Maytag, Whirlpool, Samsung, GE, Electrolux, Amana, Frigidaire and the rest. If it washes clothes, this cleans it.
What does it actually clean?
The pump, drum, tub, valve, agitator, filter, and hoses. The tablet dissolves the detergent residue, grease, and limescale that build up in all of them, which is where the smell lives.
Why do I need to clean my washing machine?
Detergent, fabric softener, body oils, and hard water minerals collect inside the machine over time. That buildup makes the washer smell, makes towels smell, and makes the machine work harder than it should.
How do I use it?
Empty the drum, drop in one tablet, and run the clean-washer cycle if your machine has one (hottest normal cycle if not). Wipe away any residue afterward. That's the whole job.
Is it safe for septic systems?
Yes. The formula is biodegradable and septic safe.
Why is my machine foaming too much?
This rarely happens, but when it does excess foam can happen for a few common reasons:
1. Detergent buildup
Most people use more laundry detergent than needed. Over time, leftover detergent residue builds up inside the washer. When the cleaner tablet starts breaking it loose, that old detergent can foam up along with the cleaner. This usually means the cleaner is doing its job, and future cleanings should foam less if the washer is cleaned regularly.
2. Soft water
Soft water can create more suds, especially when combined with old detergent residue and a cleaning tablet. This can cause extra foam during the cycle.
3. Drainage issues
A partially clogged drain hose or slow-draining washer can cause water and foam to back up instead of draining properly.
Why tablets instead of liquid or powder?
Tablets are pre-measured and dissolve slowly through the full cycle, so the cleaner reaches parts a quick rinse never touches. Renuv tablets are also up to 3x larger than most washing machine cleaner tablets, and there's nothing to spill or measure.
Why is the box shrink wrapped?
The box is recyclable cardboard and the tablets are sensitive to moisture, so the wrap protects them during shipping and warehousing.
