Dirty clothes are often subjected to a smell test: if the grime has transformed into organisms with noses large enough to be seen by the human eye, then it’s time for a wash. Keep garments fresh and nostril-free with today's Groupon: for $20, you get $40 worth of dry-cleaning services at Imperial Cleaners. This Groupon is valid at the four locations in Fox Chapel, Oakmont, Pittsburgh, and Sharpsburg.

Family owned and operated for more than 50 years, Imperial Cleaners employs a staff of experienced garment-cleansing specialists. Drop off unwashed digs and the highly trained team will pore over clothes, gently removing encrusted stains and dirty smudges from water-averse items such as sweaters ($5.50) and pants ($6.95). Prep a two-piece suit ($13.75) for a public appearance by removing the vestiges of past mud slinging, or wash away the inevitable buildup of creamy nougat filling that make dresses hard to wear ($13.50). In addition to clothing, Imperial Cleaners can also wash household items such as bedding and rugs.
