How can you easily remove moldy silicone caulking from bathroom tile grout lines?

A hair dryer and a butter knife. Use the blowdryer to heat up and soften the caulking from around the tub or tile. Sometimes it will just pull up like a string sometimes you need to use the butter knife.I used bleach to really clean and disinfect the area before I re-do the job.Always test first on a spot that will NOT be seen.
