Smoking can not only stain your teeth and skin, but for men with moustaches smoking can leave behind tar stains that make your moustache yellow, brown or even grey depending on hair colour. While quitting smoking can prevent these stains, if you continue to smoke then knowing how to remove stains that build-up can keep your moustache looking vibrant.
Trim off bits of your moustache that are stained as much as possible. You can opt to trim a lot for quick removal or if you aren't comfortable trimming off too much just trim the tips and any strays to clean up your moustache.
Mix 1 tbsp of baking soda with 1 tbsp of white vinegar in a bowl. The mixture will rise and bubble a little so stir until it stops and is a pasty texture. Apply the mixture to your moustache rubbing it in thoroughly and let sit for 10 minutes. Rinse with water. Apply to your moustache once a week or twice if you tend to get stain build-up quickly.
Mix 1 cup of water with the juice of half a lemon and drink this mixture making sure it coats your moustache as you do. Add lemon to water every time you drink water or at least drink the lemon water mixture once in the morning and once at night.
Pour a dime-sized amount of gently clarifying, dye-free shampoo over your moustache when you bathe. This will help remove build-up that occurs throughout the day as you smoke as well as fight off future stains.
Facial hair dye can be used to cover tough stains, just ensure you use dye only meant for facial hair and never use regular hair dyes or bleach.
