Linoleum bathroom floors are durable and relatively inexpensive. The floors also resist stains, but they are prone to discolouration from rubber. Rugs that contain a rubber backing will leave behind yellow stains that will make the linoleum floor look unpleasant due to the antioxidants in the rubber material reacting with the plastic in the linoleum. Instead of replacing your linoleum floors, you can save money and clean them with items that you have at home.
Combine 2 tbsp of lemon juice and 1 tbsp of baking soda in a container. Mix the ingredients until the baking soda dissolves into the lemon juice.
Apply the paste onto the yellow stains. Allow the solution to sit for 10 minutes.
Scrub the stains with a damp sponge to remove the paste. Wipe the floor with clean water and a washcloth to remove any lingering paste. If you still notice the yellow stain, apply rubbing alcohol to the floor.
Apply the rubbing alcohol to a washcloth to dampen it. Rub the washcloth over the yellow stain in a circular motion. Apply more rubbing alcohol to the washcloth as needed.
Depending on the severity of the yellow discolouration, you may not be able to remove it completely from the linoleum floor. You may need to purchase a commercial floor stripper and cleaner to remove the stain. Contact a home improvement store for help with this task.
Never apply ammonia to a linoleum floor because it can cause discolouration.
