The ones with the rubber underneath. It doesn't say on the tag. Can you wash them in the washer and dryer? Or will it melt in the dryer?
Wash in cold water. Air dry. The rubber will melt in the dryer. Over time, the rubber will flake off from being put in the washer, but it will work. Or, if you have access to a carpet shampooer, that would work too.
you can do them in the washer and dryer but the rubber backing will fall apart after a few washes. dry it on a cool setting and then hang over the side of the tub or kitchen chair or porch rail to finish drying.
I have used my washer and dryer to wash mine before but I usually wash it in the washer and hang it dry. The plastic didn't melt on mine when I dried it in the dryer, I just hang it to dry because I usually wash it seperately from my other clothes.
i have washed them before, unless its an old one and the rubber backing is starting to crack and peel or flake off i just wash them with hot water in my home washer and hang them outside or over the handle in the shower to dry. but no they wont melt in the dryer. i have done that also. but it does make the backing deteriorate quicker so the rug wont last as long. if the backing is already falling apart its best to just toss in the trash and get a new one. i personally dont even have rugs in my bathroom anymore. its easier to mop the floors without them. and they are just germ havens. the ones that go around the toilet are just nasty, and instead of having a rug outside of the shower to stand and dry off i always hang up the towel on the shower rack i used the day before and put that on the floor the next day. it is more sanitary anyway. those wet rugs are really nasty when it comes to bacteria.
I put mine in the washer and the dryer. I wash them in warm water and dry them on the low heat setting. They are clean and fluffy every time. The only thing to watch out for is bleach. Washing the rugs in bleach will erode the latex backing on the rug and destroy it. Just some regular laundry soap without bleach is best. Good Luck!!! :)
