Is lemon a natural deodorant?

Unbelievable but yes, you can replace your deodorant with lemon. Wet your armpits with lemon juice or rub directly with half a lemon. If it irritates your skin, make a solution in a spray bottle with half lemon juice and half water. Spray directly to areas of skin like armpits or feet. It doesn't stain clothes.
