I have a large, old cutting board made of a heavy white material (sort of a polymer plastic). It was extremely discolored & I was going to toss it out. I tried all kinds of things to get it clean, including putting it into the dishwasher. Nothing worked. As a last resort I filled my kitchen sink with hot water & added bleach & let the board soak for a few hours. Ole! It looks brand new.

Here are questions related to Cleaning Plastic Cutting Boards.
My mother has a cutting board. It is made of a type of white hard plastic. Over the years knives have cut into the surface and now those areas have darkened. My mother believes this is mold and has tried cleaning the board with bleach to no avail. Does anyone have any suggestions?
