ECOS Laundry Detergent Sheets are the future of laundry detergents. Our innovative detergent is LIQUIDLESS & POWDERLESS. No more heavy laundry detergent bottles. No more liquid or powder laundry detergent mess. You only need one lightweight laundry sheet to do the job. Each sheet is readily biodegradable and septic and greywater-safe. It?s safer for people pets and the planet! One square lifts stains brightens whites and guards colors. Whether you prefer Free & Clear or the delightfully scented versions it works beautifully. Each square dissolves completely in all water temperatures. Great for high-efficiency (HE) and standard machines.
