Linoleum floors, often referred to know as vinyl floors, often develop yellow stains that are difficult to remove. The yellow stains typically form from rugs that do not allow sunlight to penetrate the floor or the backing on the rugs causes a reaction. Before you begin to sand and buff the floors to remove the stain, try a less drastic approach. Removing the stains will require several applications, depending upon the severity.
Remove any rugs from the linoleum floor. Use a broom to sweep away dirt and debris.
Mop the stained area. You need the entire yellow stain to be wet.
Sprinkle baking soda over the stain.
Let the baking soda set for 15 minutes.
Wipe the baking soda off the area with a dry cloth. Repeat wetting the area and adding baking soda for deep yellow stains.
Clean the area with the baking soda weekly to prevent the yellow stain from returning.
Allow the area to receive sunlight frequently to reduce the yellow spots on the linoleum. Inspect the labels on floor rugs to ensure that they will not stain vinyl or linoleum floors.
Do not use an abrasive sponge or brush to clean the linoleum floors.
