The fire broke out just after 1:00 a.m. at the Bryn Mawr Cleaners on the 500 block of West Lancaster Avenue.
The fire quickly went to 2-alarms on the first floor and spread to the second floor storage area.
The fire was placed under control within thirty minutes and no injuries were reported.
Smoke from the flames spread to the carpet business next door and caused damage.
There is no word on what sparked the blaze at the cleaners.
