Sure, we could use misleading terms like 'more white', 'more cleaning power' or 'more clean'...but here at Nellie’s, we believe less is more. As in, less plastic, more planet friendly. Less ‘filler’, more highly concentrated cleaning power. Unlike Laundry Strips, our laundry cubes dissolve in hot or cold water, are PVA-free and tough on stains and odours. Cubes are 7/8 inch or 22.22 mm 'cubed'. Cubes are intended to be put right in with the load, bypassing the dispenser. Box comes with 16 cubes/loads How To Use: Use only one Laundry Cube for each regular sized load. Throw directly into the drum before adding clothing. Wash according to instructions on garments. Always test on garments that may bleed or fade. Nellie's Laundry cubes are safe for HE and standard washing machines and dissolve in hot or cold water.
