Need to clean discolored vinyl floor
Anybody have an idea how to clean a yellowed portion of a white vinyl floor? We removed an area rug in Mom's kitchen, and there is a 3" ring of yellowed discloration around where the rug was! There was no vinyl backing on the rug and the center of the rug, where her kitchen table sat, is just as white are the rest of the floor. Any ideas to clean that area? I haven't found anything that works.
