I hate mine, I can't tell you how to get it clean because I have given up. I spot clean and my husband will damp mop occasionally. One thing I have figured out is that the Shark Steam cleaner gets it clean... but don't use it over the seams because it really loosens them. This is not a problem with the 1950's linoleum - it's as tight as it was from the start... but I will never put sheet vinyl in anything ever.
