We bought a lot of clear, glass candle holders for our daughter and son-in-law’s wedding reception. I saved them to loan to friends, but the only problem was wax left in the holders. I found that one of the best ways to remove old wax was to put the holders in the freezer for a few hours. Then I took the holders out of the freezer, turned them upside down, and the wax fell out. I put the glass holders in the dishwasher to get out any wax residue, and they looked good as new!
I’ve been looking at different types of wax, is paraffin the best?
