Another great use for worn or surplus toothbrushes

For most gluing applications, the built-in dispenser tips on glue bottles work fine for placing glue where you need it. Inexpensive aftermarket glue dispensers or ketchup bottles also work great for squeezing glue into tight spots. To spread the glue on smaller flat surfaces, try a cheap toothbrush like the one dentists give away, or you can buy four for a buck at dollar stores. It will work especially well if you cut off the brush end and epoxy it back on as shown in the photo. As soon as you’re done, wash the brush with water.
