The detergent function works by using a siphon in the bottle. This siphons out the detergent solution at a 10:1 ratio. Or 10 (ten) parts water to 1 (one) part solution. It dispenses the detergent solution under LOW pressure so it will only spray out about 2 to 3 feet from the bottle. This is totally normal as the detergent needs “dwell time” on the surface to be clean. Dwell time refers to the amount of time the detergent solution stays on the surface to be cleaned. The longer the dwell time, the better the cleaning when rinsed off with a HP spray from your AR Blue Clean pressure washer.
