I recently bought a used felt top pool table from someone that had it in their workshop. They had started using it more like a table, so it got rather dirty with general debris, but also oil and grease. What should I use to clean this without damaging the felt, specifically the oil and grease?
Personally, I would forget cleaning and get the table reclothed. You may get the stains out, but the oils can damage the material in a way that can affect the playing surface.
