Dr. Bronner's Sal Suds Biodegradable Cleaner is a mild yet powerful all-purpose cleaner. Add 1-1/2 teaspoons to one gallon of water for general house cleaning. Naturally derived surfactants cut grease and dirt without leaving a harsh chemical residue. Our cleaner has the same pH as standard soap, which delivers a sudsy clean that washes away quickly and won't strip skin. It's scented with pure essential oils of spruce and fir, never synthetic fragrances.
