Our shower door was caulked with a clear caulking which, after 3 years, has turned yellow. It is very unsightly. I've tried pulling it off but it is spread very thin on the edges and it just won't come off. How can I remove this?

Razor blade?
You could try a window scraper that has a safety razor blade in it. I have had success with that before. put the blade pretty much against the thin parts on the edge and it should get it up pretty easy. Make sure it is clean and undamaged with no pitting on the edge.
You can buy a caulk removal tool at your local hardware or home improvement store, Neida.
Mogie is right. It takes patience and time. We removed old calk from all the edges of of our 5 foot bathroom vanity but used NO chemicals. The best "tool" we used was a regular hair dryer! Heating small sections at a time ( 6 - 8 inches ) made the task of removing the calk so much easier. Heat area for 30 seconds or so, holding the dryer a few inches above the calk. Then use calk removing tool, putty knives, dental tools, small paring knives or 5-in-1 painter's tool to carefully pull and pry out calking. Go over the sections a few times to get it all. Be careful not to damage surrounding surfaces. When all traces of calk are removed, clean area with alcohol or something similar. Be sure area is clean and completely dry before re-calking. Good luck.
Hello Neida,
Use a Scalpel or a razor blade, but be careful. You could of course paint it!
We removed old caulk that was thin and cracked with a caulk removing tool, then cleaned off the surface with alcohol.
