This long lasting bar cuts grease and plastic! Simply rub a sponge or washcloth against the bar to make a sudsy lather, then scrub your dishes clean. The bar weighs 3.65 oz. Keep bar out of standing water to prolong the life of the bar. Our household (2 adults, 2 kids) used one bar for 2 months, but that will vary with usage. Pair with one of our Compostable Compressed Sponges. Ingredients Organic Coconut Oil, Organic Castor Oil, Sodium Hydroxide *No sodium hydroxide (lye) in finished product
