Did you know that more than 600 million plastic laundry containers are discarded in the U.S. each year - often ending up in landfills or our delicate waterways? Nantucket Footprint laundry detergent sheets are our answer to this massive ecological problem. Our laundry detergent sheets are water soluble and biodegradable. Our packaging is biodegradable, and made from cardboard. Just put the laundry detergent strips in your washing machine as you would liquid detergent or a laundry pod, but without the harmful environmental effects. Our new 48 strip box is formulated with the addition of natural biological enzymes. These enzymes help to catalyze the reaction between stains and the water solution when washing clothes, and have incredible stain-fighting power. These laundry detergent strips are highly-effective and contain no water, making them compact, lightweight, and better for the environment. They are lightly scented with essential oils, and contain no artificial fragrances or dyes. These laundry detergent strips work with both regular and high efficiency washing machines.
