I am stripping and re-sealing a corner shower stall, and am having a hell of time removing all the old caulk. I also discovered the previous homeowners decided to just caulk over the previous caulk that was on there, so I am removing 2 or 3 layers depending on the location. It was leaking in the spots that had 3 layers so I think they just added more caulk to “fix” leaks. I have the chemical caulk remover, and that certainly helps, but it still is taking a metric fuck-ton of manual labor. Any tricks/suggestions for removal of very old caulk? I am about to throw a scotch brite on a palm sander and go to town.
If you’ve got a heat gun, a moderate amount of heat for 30 seconds or so can help. Just go easy on the heat if you’ve already applied a chemical remover, don’t want to gas yourself.
Oh, good to know, I do have a heat gun
