As the numbers of cars and car washes grew exponentially in the 1980s, Hanna Industries again brought innovations to the market. Recognizing the need for consistent car wash quality, Hanna began franchising. In 1981, Entrepreneur's magazine named Hanna the #2 franchiser in the world (just behind McDonald's) and in 1982 named Hanna #1. Hanna's success continued throughout the 1980s with the creation of more vehicle wash and marketing innovations.

By 1988, Hanna Industries was servicing more than 18,000 vehicle washes in 56 countries. Annual sales reached in excess of $30 million. In 1989, Hanna ranked #1 worldwide for installed conveyorized car washes.
