Step 6: Cleaning
Take your lightbulb to the bathroom to clean it out. There is a dust in the bulb that coats the inside. To the best of my knowledge,it is non-toxic, but probobly isnt the best thing for your lungs. Fill it halfway with water, cover the stem with your thumb, give a couple good shakes, and rinse. There may be some stubborn bits that "wont come off", but you can get those easily with an old toothbrush.
