PUSH (not scrape) wax up on the fingernail of your index finger, and then wipe it onto your thumb of the same hand. (Push like a bulldozer pushes up dirt.) Some customers prefer using different objects to push up the wax before putting on fingers. Find what works best for you. Rub the wax back and forth 2-3 times between your index finger and thumb. Then apply using your index finger. Or you can use both index finger and thumb if you’re trying to handlebar or want more control of where the wax is applied.
Make sure wax is at room temperature before applying. You may want to put it in your pocket, over a warm vent, on top of the coffee pot etc. to make the wax even easier to apply. Running the (closed) tin under hot water has also been found to work well. If water gets in the tin just shake it out and blot with a towel if needed. It's wax...water's not going to hurt it! However, the wax needs to be dry for application or it will ball up on you instead of going on smoothly. Your fingers and facial hair also need to be dry for best results in applying. Others have found warming the wax with a hair dryer can be helpful as well as using a toothbrush, boar's hair brush ( I cut the handle off mine and hold at the bristles for better control), plastic bristle brush or moustache comb to work the wax thru the 'stache after applying.
Also see the "About Us" link for more helpful suggestions on applying our wax.
Our wax can be washed out with warm water and soap/shampoo. Most don't completely wash it out every day as it can be drying to the hair. Apply conditioner if needed. I usually completely wash mine out once a week and just reapply the wax as needed each morning. More will be needed after completely scrubbing the wax out. Again, find what works best for you. A customer in Belgium found that when you rub a good quality plant oil with your forefinger and thumb into the waxed moustache and let it sit for a couple of minutes, you can easily wash the oil and wax out. He recommends using the pomegranate body oil from the Weleda brand, but says any good quality sesame or almond oil should do. In addition to cleaning it well, it also provides a healthy treatment for the 'stache.
Check out this great video concerning using FMW. The video was made in association with the U.S. Lawn Mower Association's 'MOWvember' Moustache Competition to raise money for men's health. Thanks to Mick for showing us his fine 'stache for the video!
