All purpose non-toxic cleaner. I use this to clean every surface in my home that can come in contact with water. All-Purpose Cleaning Spray: 1 Tbsp. Sal Suds in a quart (1 L) of water. Hint: Put water in the bottle first. Spray and wipe with a damp cloth. Optional: Add ¼ tsp. tea tree essential oil. LTKfamily LTKfindsunder50 LTKhome
