Coit Services, Elkton

Coit began as a humble dry-cleaner nearly 70 years ago, and since then, it expanded to become a big wig in the cleaning industry, with franchises across the continent. The company specializes in drapes, upholstery, and tile, not to mention wood and stone surfaces. But its main focus is carpet cleaning—the company uses a truck-mounted system that extracts soil ground deep into carpets, then technicians deodorize and finish up with a protective coating.
