Linoleum vinyl floors in the bathroom can turn yellow if the wax coating begins to fade. Areas on the bathroom floor can also have a yellow stain due to urine, the rubber backing on rugs, and sunlight. You can use items you have around your home to remove the yellow stains and restore the floor back to its original condition. If you do not treat the stains immediately, you may need to either replace the floor or strip it of the wax, which can cost a lot of money.
Clean debris from the floor by sweeping it with a broom. This will allow you to clean the area without anything obstructing the stain.
Combine 2 tbsp. of liquid dish soap with 2 cups of warm water in a container. Soak a washcloth in the soap solution, and wring out the excess. Scrub the yellow stain to clean the area.
Combine an equal amount of baking soda and water in a bowl. This will form a paste. Apply the paste to the yellow stain with a sponge.
Allow the baking soda paste to sit on the stain for one to two hours, then scrub it off with a clean sponge and warm water. If the yellow stain is still present, you can try applying a vinegar solution.
Soak a scrub brush in vinegar, and work it onto the yellow stain by scrubbing in a circular motion. Rinse the solution from the floor with clean water.
