Remember that prevention is key. You should not eat or drink near your pool table. But, if you do find yourself in this situation, act quickly. Absorb as much liquid as possible with clean dry paper towels. The longer the liquid sits, the more it will stain the cloth.
We offer billiard cloth embedded with Teflon to help you keep your pool table clean. This is a great preventative measure, but secondary to not setting your drink on the rail of your pool table.
