You want to remove wax from glass?

At a temperature of around 65° C the wax melts. To remove the candle wax out of the glass, first boil water. Then pour it into the glass an add dishwashing liquid or soap. The heat causes the wax to liquefy and float to the top. Before removing the wax, first let the water cool completely. You can also leave it overnight for better results. As soon as it has cooled down, you can take out or poor off the wax and remove the last residues with vinegar, for example.
