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.

  1. Sweep the gym floor with a dry dust mop to remove dirt and debris.

  2. Cut a tennis ball in half and attach it to the end of a broom handle with duct tape.

  3. Dampen the tennis ball with mineral spirits.

  4. Rub the tennis ball on the black marks until you have removed them from the floor.

Warning

  • Do not use normal household cleaners on the gym floor, or you may damage the finish.
