And if somebody has recaulked an area, there are even more blobs on top of the older blobs.

It's most convenient to do this when outdoor temperature levels are above 80 degrees, otherwise you might utilize a hot air weapon or blow clothes dryer to carefully heat the caulk.
The is to get the old caulk as flush to the rubber surface area as possible. Have a little tub, denatured alcohol, and rags nearby to clean up as you go. Shop the can and rags in the little tub. Prevent letting the denatured alcohol make contact with the rubber roofing system for too long.
