Bleach tulle in the solution of ammonia with the addition of hydrogen peroxide. Pour into enamel bucket of hot water, add two tablespoons of styrene three-percent hydrogen peroxide and a tablespoon of ammonia. Shut the curtains into the water and stir with a wooden stick or tongs. Leave the tulle in the whitening solution for 15-25 minutes (boil is not necessary), then how should rinse.
Can be bleached and tulle with the help of salt. Rinse the curtains with warm water, squeeze lightly. Pour into a basin of hot water, add washing powder and a handful of regular table salt and place the tulle into the solution overnight and in the morning wash in warm water.
Saline solution can be used that way. Washed the curtains soak for 10-15 minutes in warm salt water, gently wring out, allow to drain remaining water – wet and hang on the window. Tulle not only blanch, but still slightly podtropolis and such "salty" curtains will sparkle in the light and look much more spectacular.
