Removing caulking?

What do you all use to remove old caulking on the fiberglass gel coat? Normally I would use a flat razor blade but not sure if that is a good idea on the fiberglass? Also is there a solution that softens it up to make is a little easier to remove? Thanks!

There are many commercial products out there. Amazon.com: silicone sealant remover
Puddy tape caulking around windows and trim will dry and ooze out with heat, crack and get brittle with cold temperatures. So not to scratch the gel coat, I use a plastic spreader (like a plastic putty knife) to clean off old dirty calking from the edges of molding and trims, but first wash the RV to remove all dirt along molding and trim. After scraping away old excess and dirt caulking, I use Paint thinner or acetone on a clean white rag to remove the dirty residue left behind. Because RVs are always flexing with movement and temperature, I use Silicone #2 , as it has mold resistant additives. I use clear on painted areas and white on white to reseal the edges of the calking for looks, to keep it from drying out more, and save cleaning time in the future.
Never use silicone on rubber roof.

OK thanks, I was going to use Dicor No sag caulking. I heard it works well and doesn't dry out as fast as silicone?

I just did my EPDM rubber roof and used a puddy knife - the 13 year old caulking came right off where it was loose/dry. I left the firmly attached caulking on and re-caulked right over it. No damage to the EPDM rubber, so I would think if you are careful it would work on paint/gel as well. P.S. I tried Mineral Spirits to loosened up the old caulking a little - it worked a little, but not much. II stopped using it after about 2 seams. What did seem to help was a hot sunny day - 85 degrees+.
