Rugs and mats with rubber backings can leave behind yellow stains on linoleum and vinyl floors. The yellow discoloration makes the bathroom floor appear unpleasant. Instead of replacing the floor or stripping the wax, remove the stain with items you have around your home. Cleaning the floor regularly and avoiding rubber mats will help keep it in pristine condition so it lasts for many years.
Remove the rubber mat from the bathroom floor. Sweep the floor with a broom to remove all loose dirt and debris from the area.
Mop the bathroom floor with a mild detergent and warm water. Combine 2 tsp. of liquid dish soap with 1 gallon of water. Always wring out the excess water to prevent damage to the seams.
Create a paste that contains an equal amount of baking soda and water. Spread it over the yellow stain on the floor, and leave the baking soda on the stain overnight. Scrub the stain the following morning with a damp nonabrasive sponge, and then rinse the floor with clean water.
Spray white distilled vinegar onto a nylon sponge if the yellow stain remains, and scrub the area. Sprinkle baking soda over the vinegar to create a reaction. Allow the baking soda to fizz for one to two minutes, and then scrub the area with a damp sponge. Rinse the floor with clean water.
Dry the floor with a towel after you remove the stain.
