Windex was invented by the Drackett Company in 1933 and has been marketed throughout the intervening decades. Windex was originally sold in glass containers before adding plastic and metal containers over time.
Drackett sold Windex to Bristol-Meyers in 1965. S. C. Johnson acquired Windex in 1993 and has been manufacturing it since.
The original Windex was colored a light, translucent 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.
