There are 4 ways to remove wax from fabric.
1. Dryclean it out. But ask first, not all dry cleaners will do it, and the newer chemicals may not work well.
2. Boil the fabric and skim the wax off the surface after it cools.
2. Iron it out between layers of absorbent paper (leaves a residue that looks like a grease spot.
4. Steam it in a steamer between layers of absorbent paper (won't get it all).
Boiling is the traditional age old method. You will need a dedicated pot.
Important Safety Tip!
Don't overheat waxes! Use a double boiler or something like an electric frying pan where you can control the temperature. If they get above 240 degrees F. they can start smoking or even burst into flames and/or give off hazardous fumes. If it starts smoking, cool it. Work with excellent ventilation. If fire were to occur, smother it, don't use water to put it out.
