Our most exceptional everyday laundry detergent for everything from shirts to sheets, now in a gallon size for up to 126 washes! Optimized for cool water and suitable for HE machines, The Laundress Signature Detergent is an all-purpose laundering formula that targets stubborn dirt, stains, and grease. Specially designed for whites and colors, with powerful, deep-cleaning enzymes that target fresh and set in stains. Discover a beautiful clean in just one wash!


Follow garment care label instructions. Sort items based on colors and fabrics, then pre-treat stains with a stain remover like Stain Solution. We recommend washing whites, light colors and heavily soiled cotton items in warm water. For HE/high efficiency washing machines, use dispenser. For standard washers, start machine, add detergent, then clothes. Contains 126 loads as measured to a medium dose. Use a measuring cup like the Laundry Measuring Cup and follow dosing instructions.​

​How To Use Your Gallon Pump:​

  1. When opening your Gallon for the first time, start by removing the cap and seal.​
  2. Next, unscrew at the neck to release the pump before inserting into the bottle. This will help prevent overflow.​
  3. Once the fill level reduces, you may keep the pump screwed closed if desired.
