Vanish is an American brand of toilet bowl cleaner produced by S. C. Johnson in North America.
Drackett purchased the product from inventor Judson Dunaway of Dover, New Hampshire, who introduced Vanish in 1937 as a competitor to Sani-Flush, a toilet bowl cleaner made since 1911.
Initially, Vanish sold their product in a white 22-ounce showing the bowl cleaner coming from the bottom of the "I".
An in-tank toilet cleaner, intended to compete with 2000 Flushes and Clorox automatic, was introduced under the Vanish brand in 2000.
