Best washing machine cleaner I have ever used. Sample was in the machine I purchased, and after using it, I was amazed. Used monthly, the freshness it adds to the tub remains through numerous loads of clothes, regardless of the water temperature or the soil level. A little pricey but well worth it...this little tablet does a great job.

Product works as advertised. We have a High Efficiency washer and have been using these periodically for the past several weeks and they have made a huge difference. The occasional stale smell from the washer is treated for many washes after using one of the tablets. You just have to track how many washes until the smell comes back and use these accordingly. We recommend this product.

My wife uses these in our front loading washing machine (and has since bought them for her mother as well), probably every month to two months. They are great for getting rid of that musty moldy smell, or for cleaning out the washer after washing oily clothes or dog blankets (I wouldn't know anything about how those things get there though).

This works great! The mustiness is gone in my washer. I plan on using a tablet once a month to keep it fresh. It had a chemical smell at first, but I just ran an empty cycle and the smell is gone.

Washer started smelling a bit funky several months after we got it.

I didn't understand why I couldn't just run bleach in my machine to clean it out occasionally, until I actually ran one of these tablets (free sample with my washer)

The key is that the tablet goes in the washer drum, and doesn't dissolve right away. So as the washer runs through several repeated cycles of fill, agitate, and drain - the tablet is still there, sudsing up the water on cycle #2 and #3. If you just put bleach in the soap dispenser, it would all be gone after cycle #1.

Also, this gets very sudsy and that probably helps it reach some areas of the machine that wouldn't otherwise get touched.
