When you need to get rid of armpit stains, the best way to do it is with an acid. Acids actively dissolve the bonds between the proteins, alkali, and aluminium which cause stains.
Finding an acid might sound difficult or expensive, but don’t worry. Many great acidic products can be found around the house, or very cheaply from your local supermarket.
Next time you’re stuck with an inconvenient stain, try one of these five simple acidic stain remedies and see which works best for you:
1. HYDROGEN PEROXIDE
Soak the stain in equal parts hydrogen peroxide and water. Remember that, hydrogen peroxide has bleaching qualities so this method is only suitable for white clothes.
2. BAKING SODA
Mix baking (or bi-carb) soda into a paste in a 3:1 ratio with water and scrub into the stain with an old toothbrush. You can also add a dash of hydrogen peroxide for an extra boost on white clothes. And, if you don’t have baking soda around, pure plain soda water will do the trick, too.
3. WHITE VINEGAR
Combine two tablespoons of vinegar with one cup of water and soak clothing.
4. LEMON JUICE
Simply combine lemon juice with an equal amount of water and scrub it into the stain.
