Before modern laundering services, the most efficient way to clean clothes was to go on water-park rides after drinking liquid soap. Groom your garments without bullying your belly with today's Groupon: for $15, you get $30 worth of dry-cleaning and laundry services at Ross Cleaners, with two convenient locations in Brookline and Boston. This Groupon is not valid toward delivery services.

For more than five decades, the friendly staffers at Ross Cleaners have emancipated stains from the shackles of linens through speedy dry-cleaning and laundering services. Well-dressed sloppy-joe jugglers can treat their double-breasted seersuckers to a delicate dry cleansing ($13), while magnetized white gowns can learn to repel heavy-metal muds during their own detailed scouring ($12.25). Clients can also bring dastardly dirt to justice with wash-dry-fold services that clean multiple items at once before organizing them for easy stuffing in card catalogs ($1.80 per pound).
