If you started with a clear bulb, you don't need to clean it out. If you used a bulb coated with white kaolin powder, however, you'll want to clean this powder out before using the bulb for anything. Kaolin is considered a safe substance, but you should still avoid ingesting it or getting it in your eyes. Keep your goggles and gloves on. Stuff enough paper towel into the bulb to fill most of it, leaving a long enough "tail" sticking out from the bottom for you to grab. Watch out for any sharp edges or sharp bits of broken glass. Using the tail of the paper towel, twist it around the interior of the bulb, wiping away the powder in the process. Dry paper towel will usually work well enough, but if you have difficulty cleaning the bulb with dry paper towels, consider moistening the towel slightly and trying again. If some of the kaolin will not come out, fill the bulb one-quarter to half full with salt. You'll use the abrasiveness of the salt to help scrub the corners and angles of the bulb. Carefully cover the bottom of the bulb and give the entire thing a good shake. The salt should scrub away most of the remaining traces of kaolin.  Place your gloved thumb over the bottom of the bulb to prevent salt from flying everywhere. You could also hold a paper towel over the bottom to accomplish the same goal. Dump out the salt when done. Dispose of this salt; do not reuse it. If there is any salt or kaolin inside the bulb, use your paper towels to clean it out.  The material inside the bulb should be loose enough at this point for the paper towel to catch. Once you are finished with this step, the bulb is completely open, clean, and ready to use for whatever project you have in mind.
