Mildew spots must be treated when fresh, before the mold growth has a
chance to weaken the cloth.
Soap and water.—On washable material, soap and water will remove very
fresh stains. Drying on the grass in the sun helps to bleach the spots.
Bleaches.—Try a bleaching agent if soap and water do not remove the
stain. Be sure to test for colorfastness on a hidden part of the
garment.
_Lemon juice._—Moisten the stain with lemon juice and salt and place in
the sun. This often removes slight stains.
_Javelle water._—Old stains on cotton, linen, or rayon may be bleached
out with Javelle water. Dip the stain in the Javelle water for 1 minute
(no longer), remove the chlorine from the cloth with a sodium
thiosulphate solution, rinse well in water. (See p. 6 for more detailed
instructions.) Do not use Javelle water on silk or wool.
_Sodium perborate._—Soak the stain in a sodium perborate solution (4
tablespoons perborate to 1 pint lukewarm water). Or dampen the stain
with water and sprinkle the perborate powder directly on the stain.
Rinse after either treatment.
