Didi Seven was developed in Germany in 1967 as a concentrated, easy-to-use stain remover for almost any product or material. Interwood Direct, a Canadian company, sells the product in North America. Although Didi Seven is highly versatile and effective, you must still follow normal stain-removing protocol by testing a small, inconspicuous area before attempting to remove the stain.
Absorb any excess stain-causing material with paper towels. Gently blot -- don't rub -- the towels on the stain. Use a small, soft brush to remove any excess particles if the stain is from a solid material such as vomit or strawberry jam.
Rinse the stained material with water. Use cold or hot water depending on the stain-causing item (see References).
Apply Didi Seven. Put a dime-sized amount of Didi Seven on the stain using a soft washcloth or rag. For textured fabrics, such as carpeting and upholstery, spread the Didi Seven using a soft-bristled brush. Apply a teaspoon of warm water and gently spread the Didi Seven over the affected area until it dissolves into the fabric. Let the Didi Seven set in the fabric for no more than five minutes. Use less time for delicate fabrics such as thin cotton or silk.
Rinse the Didi Seven residue from the material completely with cool water. Blot the fabric dry. If the stained item is machine washable, launder as usual per the manufacturer's instructions. If the stain remains, repeat the first three steps using a tablespoon of boiling hot water to dissolve the Didi Seven into the fabric.
Pour club soda onto carpets and upholstery to dissolve the Didi Seven instead of using warm water. For delicate fabrics such as silk, pour distilled water onto the Didi Seven.
