Review on 🚙 Efficient and Convenient Windshield Washer Fluid Tablets - 50Pcs, 1 Piece Makes 1.05 Gallons, 1 Pack Makes 52.5 Gallons by Daniel Russell

Very easy to use. You get 100 tablets to make 100 gallons. I used a gallon bottle of windshield washer fluid to make my own. I measured out a gallon and there was room to add about 4 ounces. About the washing additive Rain-x, which I also found here. If you're used to using rain-x, this is the perfect combination for you. Rain-x weighs 16 ounces. Bottle so you have 4 uses to craft 4 gallons with it. I think it was the best alternative to buying a gallon at a gas station for almost $4 a gallon.
