Cleaning beads in my house is no big deal and takes me about 10 minutes each morning.  I have never used a dremel. I don't even own one. In my fist class with Jennifer Geldard www.glassgirl.com she shared with us this method.  By using the substance sand paper is made from, silicon carbide, you can in effect turn your mandrel into a cleaning device. Simply remove the bead from the mandrel and clean the excess bead release from the mendrel. Now wet the clean mandrel you used to make the bead and dip it into the cleaner coating the botton inch or so. Now use the mandrel with the coating to clean the bead by inserting it back into the bead and scrubbing the release right out. Periodically rinse the bead under running water and repeat until the bead is spiffy and sparkly clean.  The average bead will take about 2 to 3 dips into the cleaner and a 4 oz jar should last a long time.  This method is just as effective as a dremel without the danger of breakage and chipping. It works on soft glass and boro.  Try it! You will never dremel another bead!
