Old Dried Caulk Removal

We recently removed an old sliding glass door from our fiberglass shower/bath unit. After some gentle persuasion the track came free but left behind old dried caulk that has proven to be a pain to remove. My goal is to remove the residue with as little damage as possible to the fiberglass. So far my attempts have met with little success. I have tried scraping, heat, mild detergents and goof-off with no luck. Does anyone have any advice? Any help would be greatly appreciated. Thanks

Welcome to the forums! It is probably silicone rather than caulking. None of the chemicals will remove it without harming your tub. Don't scrape it either, since you will most likely scrape the finish on the unit. If you are very careful, you can use single edge razor blades at a really sharp angle and work an inch at a time. Any residue can be wiped off using MEK (Methyl Ethyl Keytone), but use it in a ventilated situation, 'cause you can take a trip and never leave the farm with the vapors.
