Hair wax hardens almost instantly, making it impossible to wipe it up with a towel or rag. Although it may appear difficult to remove, it's actually a fairly simple process. Once the wax is reheated, it will begin to soften and liquefy again, allowing you to easily scrape away the large clumps. From there, the residue can be wiped away.
Turn your blow dryer on to the highest setting. Position the blow dryer so the hot air is blowing directly on the wax.
Use a plastic razor blade or scrapper to scrape away chunks of wax as it begins to weaken. Immediately lift up the wax and place it in a garbage bag, so it can not hardened and stick to the sink.
Lay a paper towel over any liquefied wax. The paper towel will absorb the wax. Immediately lift up the paper towel so the wax does not harden with the paper towel attached to it. If it does, reheat the wax with the blow dryer. Continue Steps 2 & 3 until all of the wax is removed.
Dampen a cotton ball or cloth with baby oil. Rub the baby oil over any wax residue remaining. Allow it to work into the residue for 10 minutes.
Fill the a sink, bucket or bowl with water as hot as you can stand to touch and a squirt of liquid dish soap. Dip a sponge or cloth into the soapy water. Clean the sink thoroughly to remove baby oil and left over wax residue.
Rinse the sponge or cloth under cool running water. Wipe soap residue away from the sink. Allow the sink area to air dry.
