This highly concentrated formula is designed for tough cleaning jobs on any washable surface. It is extremely useful for cutting through grease and oil commonly found in industrial settings, while remaining gentle enough to wash surfaces in offices. Our #161 is simple to use in both the gallon size and spray size. Just put the pouch into the desired container and add the appropriate amount of water. There is no guesswork, “glugging”, or overusing the product. Packaged in recyclable cartons and tubs.
