Septone Water Based Degrease-All is a biodegradable, phosphate-free, water based degreaser formulated to remove heavy deposits of grease, oil, dirt and grime from machinery, engines, lawn mowers, outboards, concrete floors and most badly soiled substrates. Degrease-all contains sodium hydroxide and alkaline builders to efficiently penetrate and cut through grease, and its combination of biodegradable surfactants and a water-miscible solvent help to remove the grease during the hosing-off operation. The emulsified grease then quickly breaks from the aqueous layer when collected in a grease-trap, and the aqueous layer can be safely drained to the sewer.
