For those pesky sweat stains that tend to appear beneath the arms and on the collar, try this lemon and salt remedy.

Add two liters of boiling water, sixty milliliters of washing powder, three tablespoons of salt, and the juice of three lemons. Take the pot from the stove and stir in the other ingredients.

After soaking for 40 minutes, wash the garments in cold water and air dry them in the sun.

Another great substance for removing certain stains and lightening clothing is hydrogen peroxide.
