This depends on the product because the size of a bottle and amount you use varies based on the product. On average a 16 oz. bottle of Hair & Body wash will last about 30 showers and you should use this product with a loofa to prolong use of this product. A 16 oz. bottle of Equipment Spray will last approximately 2-3 months depending on the frequency of use and the amount/size of the equipment you are spraying. For example, if you’re disinfecting all of your Football equipment including padding, sneakers, helmet, and bag then the Equipment Spray may not last you as long as it would if you were just spraying a helmet. The Laundry Detergent will make about 40 loads of laundry. The Concentrate Formula should be used by mixing 1-2 oz. with 1 gallon of water, in turn, making about 64-128 gallons of cleaner.
