After a few months of winter burrowing, you could probably use a thorough apartment-scrub about now. Enter Brooklyn-based brand Common Good, which recently rolled out a line of sudsy cleaning liquids stripped of unnecessary phosphates, dyes, and fragrances. Beyond reinforcing your ecopride, they actually work: The doubly concentrated laundry detergent is fierce enough to rival Mom’s industrial-strength Tide. Most impressive is the company’s bulk-buying policy: Bring your plastic bottle (or invest in a reusable glass one for $7 to $8) to one of nine markets in Manhattan and Brooklyn and refill your soaps for a mere 19 cents per ounce (from $4.99 at Brooklyn Kitchen, 100 Frost St., at Meeker Ave., Williamsburg; 718-389-2982).
