Question: I have a yellow stain on the relatively new vinyl flooring in my bathroom. It was caused by a rug. How can I remove it?

Answer: The stain is probably permanent. Yellowing of vinyl and linoleum floors can be caused by additives in the rubber nonskid backing of some throw rugs. Some other rubber products, such as wheels on carts, can also cause yellowing, as can products tracked in on shoes. If you want to use non-skid throw rugs on these floors, check to see if they are labeled safe for vinyl. In your case, it seems the stains can be traced directly to the carpet, but vinyl flooring can also be discolored when moisture gets trapped underneath or the flooring reacts with something in or on the substrate. Leakage problems should be considered whenever irregular staining occurs around toilets, pipes or other water sources.
