How do I properly remove old caulk from a bathtub without damaging the surface?
So I finally decided to tackle the gross, discolored caulk around my bathtub. It has been there for years and honestly looks terrible. I started picking at it with a utility knife but I am worried about scratching the tub surface or the tile edges.
I have seen some people recommend using a dedicated caulk remover tool, others say a plastic scraper is safer, and some say to apply a chemical caulk softener first and let it sit overnight. I genuinely have no idea which method is the best starting point or if the order of steps matters.
My tub is a standard white acrylic so I really do not want to gouge it. I also want to make sure the area is clean and dry enough before I apply the new caulk so it actually sticks properly this time and does not peel away after a few months like it has before.
A few specific questions: Does the chemical softener actually work well or is it mostly hype? How long should I let the surface dry before recaulking? And is painter's tape worth using to get clean lines or is that overkill for a beginner?
Any tips from people who have done this before would be really helpful. I want to do this right the first time instead of having to redo it in six months.
