I have a wood panel door, previously painted over 20 years ago, which I want to repaint. I think latex was used, but I'll check by rubbing a small area with alcohol to see if it rubs off (latex).
The door is quite dirty (it separates the basement from the garage). I want to clean the door prior to (and after) light sanding. Assuming the existing paint is latex, would denatured alcohol be the correct thing to use? How about rubbing alcohol (which I happen to already have)? Or should I use trisodium phosphate? I've seen references to both alcohol and TSP but am not sure which is more appropriate in this situation. Thanks.
