Why is dish washing detergent recommended by jetted tub manufacturers?
Dish washing detergent has a number of cleaning properties that reduce foaming while cleaning. Most of these detergents have sanitizing agents in them as well. The problem that occurs when cleaning your jetted tub with dish washing detergent (gel or powder) is that it does not clean out the detritus buildup but creates a film over it. The theory is that the coating will prevent flaking from occurring, misleading you into believing that the jetted tub pipes are clean. Whirlpool and Jacuzzi sell a powder product that emulates dish washing detergents. Waste of money.
