Cherry Suds washes away dirt, grime and grease with a ton of suds! This thick, viscous product is highly concentrated as a ph neutral car soap and the suds last in the bucket and on the mitt or mop. M91 is one of the most concentrated car wash soaps on the market - Use 1 oz per gallon!! Or, if you prefer, one "glug" in the bottom of an empty 5 gallon pail, and fill the rest with water. Use a strong stream or higher pressure to fill the bucket with thick suds. When the level gets low, just use more water - no need to use more product!
