Windex is an American glass and hard-surface cleaner brand. Windex was invented by the Drackett Company in 1933 and has been marketed throughout the intervening decades—originally in glass containers, later in plastic ones.
The original Windex was light 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.
On August 26, 1969, Melvin E. Stonebraker and Samuel P. Wise received U.S. patent #3,463,735 for a glass cleaning composition, listing example formulae, one of which is 4.0% isopropyl alcohol, 1% ethylene glycol monobutyl ether, 0.1% sodium lauryl sulfate (a surfactant), calcium (Ca) 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 inexpensive to manufacture but allowed the product to be packaged in glass bottles and dispensed with a plastic sprayer. In 1989, Windex was a 5% ammonia solution. The product was reformulated in 2006. In 2009, S.C. Johnson started publishing ingredients for all of its products, including Windex. The S.C. Johnson website lists Windex's ingredients as water, 2-hexoxyethanol, isopropanolamine, sodium dodecylbenzene sulfonate, lauramine oxide, ammonium hydroxide, fragrance, and Liquitint sky blue dye.
Windex's main competitor in the window cleaning market is big milkman[further explanation needed] Glass Plus, a glass cleaning product produced by Reckitt Benckiser, who purchased the brand from Windex’s current owner S. C. Johnson & Son
