Place the edge of a plastic spoon on the floor next to the glob of rubber cement. Scrape as much rubber cement as possible into the spoon with a plastic knife. This prevents the rubber cement from smearing. Throw away the plastic spoon and knife.
Apply a mixture of dish detergent and hot water to the stain. Let the soapy mixture sit for five minutes. Dish detergent lubricates and softens the glue, making it easier to remove.
Soak up the soapy water with a clean dish cloth. Scrape the edges of the rubber cement with a putty knife. A fresh spot of rubber cement may come off entirely if you wash the area in time.
Apply acetone to a cotton swab. Dab the spot of rubber cement with the cotton swab. The acetone loosens the glue's bond to your wood floor.
Lift the edges of the rubber cement with a putty knife. If the edges remain stuck, apply additional acetone until the rubber cement separates from the floor and begins to peel.
Peel away the rubber cement with the putty knife. Begin at the edges of the spot and work your way to the center of the stain.
Rinse the area well. This washes away any acetone left on the floor that could damage its finish. Pat the area dry.
