Wetwipes, or barring that, maybe taking it to a drycleaners. I haven't heard of yellow stains on it, so your best bet is probably the latter, if economically feasible.

Take it to the dry cleaners super cheap and professional.

I've cleaned my rubber playmats in a bucket of soap water before and it works fine, although since my playmats weren't that dirty idk if this method is good enough to clean out yellow stains

I just think using soap and water would work.

Not sure if this is the right place to ask this, i do apologise if my post is unwarranted.

I recently found one of my old playmats but it has yellow stains on it, probably from lack of use? I was just wondering if anyone knows of a recommended method for cleaning these rubber playmats.

Thanks
