Many people move their refrigerator to clean behind it as part of spring cleaning. If you are doing this, be sure your first lay down a sheet of plywood and roll the refrigerator onto the plywood. This keeps you from tearing or indenting the vinyl.
Now is a good time to vacuum and thoroughly clean the floors. Do not use a vacuum with a beater bar. Be sure that the product you clean the floor with is the cleaner made by the manufacturer of the vinyl.
