How to Get Black Marks Off a Gym Floor
A shiny, new gym floor easily loses its luster when black marks mar the otherwise pristine surface. The rubber soles on tennis shoes can react with the highly-polished finish on wood flooring and create ugly black marks on the gym floor. Since tennis shoes are required for most gym-based sports, the problem is ongoing. Removing black marks off a gym floor is a simple process that almost anyone can manage.
-
Sweep the gym floor with a dry dust mop to remove dirt and debris.
-
Cut a tennis ball in half and attach it to the end of a broom handle with duct tape.
-
Dampen the tennis ball with mineral spirits.
-
Rub the tennis ball on the black marks until you have removed them from the floor.
