No matter how well you care for your wooden gym floor,  it is bound to get scuff marks.

Try this to get those scuffs up.

Take a tennis ball, the newer and fuzzier the better, and dip half of it in warm clean water.

Grip the ball tightly in your hand and buff the scuff mark up using smooth round motions.

For tougher scuffs, give this all purpose spray cleaner a try?
