Question: How often do you have to clean it to keep it mold-free?
Document: Easy to clean, comfortable, and mildew free after a month or two. No strange smells or anything when I opened it and it works well. Its a low profile matt that hardly intrudes at all in your tub.
I'm disabled, and was having trouble finding a decent mat for the bathtub at a decent price. The last one we had got all grimy, even though we cleaned it often. I knew Rubbermaid was a good name, and the price was good, so I bought this one, and am very happy with it. I don't have to worry about falling or slipping in the shower, and it seems to stay clean much better than the last one we had.
I does it's job-delivery was good. However, it does get mold on it after a time and needs replacement. I keep ordering them.
The last Bathmat I had used to garner mold underneath. I was cleaning that Bathmat frequently, and finally decided, enough is enough! I looked at the reviews on Amazon, and I found this bathmat with wonderful reviews.This bathmat is latex-free, compression-molded rubber for abrasion resistance. It has a texturized  zigzag pattern on the mat's top to help prevent slips. The suction cups on the bottom grip tub floors for secure placement,and it des not move or slide.
not the length of the tub but in my opinion it doesn't have to be. Doesnt get mold so easily and i have never slipped. The only probl is the smell which I don't like. I try to keep the oxygen in my house as pure as possible.
it is now all moldy and black underneath .. i keep trying to clean this ..not good  it is good size.
This mat is a great help in feeling secure in the shower. It is also say to pick up to dry, and to keep clean. We ar totally satisfied.
I buy the extra long size, it hasn't discolored, has great grip and lasts a few years if you let it dry between showers and keep it clean.
Not mildew resistant--bleach will keep clean. Good gripping power and non-slip surface. Would order again. Size is perfect for tub.
It's really Rubbermaid and looks great...a little off white but so is nature! Suctions well and fits. For those of you who can't keep this clean...turn over the mat and soak in a couple of inches of clorox water once a week and should stay nice for a long time.
Answer: We clean it weekly and it is fine.
