Seems everyone used drycleaners back in the day, however, with today's new and modern technology and home-laundering products, not to mention easy-care fabrics and materials on the market, the dry-cleaning business isn't as hopping as it used to be.
This relates to the 1980's, nevertheless, we had a diaper service in our small town and I used to buy rubber pants from the service occasionally when the department stores were out of the size I needed.
I remember the strong sanitizing and disinfecting smell upon entering the service! The washing machines would be humming away and there would be freshly laundered diapers folded and stacked up a mile high!
