Review on Premium Large Drink Coasters: Moisture Absorption and Table Protection - Set of 6 Modern Black Rubber Coasters with Non-Slip Bottom for Drinking Glasses by Tonya Connors

This is a photo of my grandmother's old stereo that she carefully preserved for over 50 years. There has never been a drink on this coaster. I kept three stacks so no one would put a drink on top of the cabinet itself. I had another problem with my Pottery Barn table. A glossy film remains that cannot be removed. This was used for both coffee and cold drinks. This is a horrible product that ruined two pieces of furniture. If anyone can recommend a way to clean up the sticky mess this thing left behind, I'd appreciate the advice. It looks like he went all the way.
