I was cleaning my bathroom's cabinets and noticed I have a bunch of old nail polish bottles that I'm not going to use anymore, and I started to think what I can do with all of these without throwing them away? then I remembered these old tricks:
Seal an envelope Worried about whether the glue will hold? or getting a paper cut? Brush polish on the underside of the flap.
Smooth a hanger If there are rough edges on wooden or plastic hangers that could snag clothes, don’t throw the hangers out. Just brush polish over edges.
