Dr. Bronner's Sal Suds Liquid Cleaner is not a soap but instead is a concentrated hard-surface all-purpose cleaner. It is made with plant-based surfactants and natural fir needle and spruce essential oils (no cheap, harsh pine stump oil), without any synthetic dyes, fragrances or preservatives. Perfect for general household cleaning (dishes, floors, laundry, etc.), it cleans and rinses with exceptional power, yet it is mild and gentle on the skin. Sal Suds Liquid Cleaner is equally effective in hard or soft water, rinsing freely, hot or cold. It is 100% cruelty-free, as certified by the Coalition for Consumer Information on Cosmetics, and it will biodegrade rapidly after doing its job. Our Sal Suds Liquid Cleaner is the ultimate multi-purpose cleaner, great for just about any household cleaning task. Use a couple tablespoons for an average load of laundry, dilute with water to sponge down countertops or to mop your floor, or even mix with baking soda to make a powerful scouring agent for bathtubs and sinks.
