The Common Bathroom Item That Doubles As A Makeshift Screwdriver In A Pinch

First, you’ll want to find a toothbrush to use around the house, like one that you’ve designated for cleaning. With a lighter, slowly melt the plastic at the base of the handle. Be careful not to burn it, as this could produce smoke and more fumes. If you don’t have a lighter, another small flame, like that from a match, could work. You may want to hold the toothbrush over a piece of foil as you melt the handle to catch any plastic that could drip onto your table or floor. 

When the tip of the toothbrush handle is soft, press it into the screw you need to remove. Allow the plastic to become firm again, and then carefully twist the toothbrush to take out the screw. If there is a lot of resistance, the plastic will probably break. While this makeshift screwdriver can work in the short term, you’ll still want find a new screwdriver for your DIY projects.
