The bottom line Simple Green All-Purpose Cleaner 1-gallon concentrate is the concentrated cleaner that genuinely replaces 5+ specialty cleaners. The 1:30 dilution ratio (for general cleaning) yields 30 gallons of ready-to-use cleaner from one gallon, the biodegradable formulation is safer for users and waterways, the multi-surface compatibility (kitchen, bathroom, garage, vehicle) eliminates the need for multiple specialty bottles, and the price per ready-to-use ounce is dramatically lower than pre-mixed alternatives. The trade is the dilution requirement (must mix with water for each use) and a fragrance some users find too strong.
Value
