Select a kitchen pot large enough to hold the clothing you want to bleach. Pour water into the pot, and bring the water to a boil. Add one sliced lemon to the boiling water. Turn off the heat on the stove top. Add the clothes to the pot, and let them soak for one hour. Launder the clothes according to the care label.
Squeeze three or four drops of lemon juice over oil stains on fabrics, and then launder them immediately.
Pour lemon juice into a spray bottle. Spray tough stains with the lemon juice, and then hang the item outdoors in the sunlight. The combination of the lemon juice and sunlight bleaches stains. Launder the fabric after you remove the stain.
Dampen stains with water. Mix an equal amount of lemon juice and table salt. Apply the solution over the stain, and place the fabric outdoors in the sun to bleach the stain. Rinse the area thoroughly, and launder the fabric as usual.
Pour 1/4 to 1/2 cup of fresh lemon juice into the washing machine with your regular detergent.
