Windex is an American brand of glass and hard-surface cleaner that 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 yellow. Today, there are varieties marketed in several colours (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. Windex is more popularly known with the ocean fresh blue colouring.

The newest iteration of Windex includes bottles made from 100% ocean bound plastic, in an effort to stop plastic from polluting the oceans. Windex is known for maintaining a streak-free shine on most surfaces throughout your home.
