Most pool table felt is a blend of nylon and wool, which can be dyed with Rit. However, we have no way of knowing how the water and dye will affect the surface of the pool table. They may cause irreparable damage. If you want to take a risk and give it a try, we suggest gently scrubbing the felt with warm water and a mild detergent. Rinse well. While the felt is still wet, apply the dye with a sponge sparingly onto the felt. The dye water should be very hot. Mix 1 package or ½ bottle in 1-2 gallons of water at a 140 degree temperature. Allow to dry thoroughly and wipe with a clean damp cloth to remove excess surface dye.
