About Didi Seven

Didi Seven is a stain remover made famous by its infomercial television marketing campaign. It is owned by the Interwood Direct corporation of Toronto, Ontario, Canada. Didi Seven Packaging Didi Seven was developed in 1963 by a German businessman named Walter Willmann, an inventor working within the chemical industry, in the town of Renningen near Stuttgart, Germany. Didi Seven's formula was a closely guarded secret and its manufacturing process was such that several of the chemicals were mixed together separate from the rest and then added to the mix at a particular point. Walter always claimed that this sequence was key to making the product and remains a closely guarded secret today.
