How about removing the silicone caulking bead after removing shower doors? A blade is awfully tedious.....?

Okay, this is my personal preference, and I just suggested it the other day to a similar question, but when removing caulk, I find it easiest to use a relatively sharp wood chisel (not brand new, they're too sharp). Sure, I'm a carpenter, but thats how I learned this shortcut: using what was available. A sharp chisel cuts through the caulk as easily as a utility knife but is less likely to cause scratches and is easier to use because it has a handle. Get as much caulk off as you can, then rub the remainder off with mineral spirits and a rag. Trust me, I've used the razor blade scraper, utility knife, etc., etc. The best results I've gotten is with a simple wood chisel.

you can buy a tool with a V shaped blade that you pull along like a little plow, it cuts the whole bead out, try e-bay

i could use bathtub and tile chalking(DAP). while you're traumatic adout matching a definite colour, your appropriate wager could be to get a colour adventure chalk, those are stumbled on interior the flooring branch of your nearest dwelling house progression keep. there will be "sanded" and "non-sanded" chalks, the two one would be merely high-quality. good success. El Toro Malo.

Try a small putty knife.
