|Invented by||Harry R. Drackett|

The original Windex was colored a light, transparent shade of blue. 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.
When Windex was invented in 1933 by Harry R. Drackett, it was almost 100% solvent. It was highly flammable and had to be sold in metal cans. When modern surfactants were introduced after World War II, the product was reformulated.
The Sam Wise patent[clarification needed] #3,463,735 lists example formulae, one of which is 4.0% isopropyl alcohol (a highly volatile solvent) 1% ethylene glycol monobutyl ether (a less volatile solvent), 0.1% sodium lauryl sulfate (a surfactant), 0.01% tetrasodium pyrophosphate (a water softener), 0.05% of 28% ammonia, 1% of a dye solution, and 0.01% perfume. This formula was not only less expensive to manufacture, but allowed the product to be packaged in glass bottles and dispensed with a plastic sprayer.
