This concentrated blend is to be used in a bucket (1-2 oz. per 3 gallons) orGarden Hose Foam Cannon/Foam Cannon(2 oz. in these). Foam cannons are sold separately. For best results, mix with warm or hot water. Cold water is fine, it will just need ample time to mix. This product was designed with hand washing in mind, you'll achieve far better results than by just a spray on/off action.
The bottle is 16 ounces, so it will last a long time!
