Windex
Windex is the brand name of a glass and hard-surface cleaner manufactured since 1933. S. C. Johnson acquired Windex in 1993 and has been manufacturing it since. The product was reformulated in 2006.
When Windex was invented in 1933 by Harry R. Drackett, it was almost 100% solvent and highly flammable, and had to be sold in metal cans. When modern surfactants were introduced after World War II, the product was reformulated.
The original Windex was colored a light, translucent shade of blue for consumer appeal. Today there are varieties marketed in several colors (ocean fresh blue, sunshine lemon and citrus orange) and fragrances (spring bouquet, ocean mist, lavender and tea tree), with a number of additives such as vinegar, lemon, lime, or orange juice.
