The Smart Wash Dosing System is developed for use with professional house and roof washing. It hold 50 gallons of sodium hypochlorite — 12.5% in the back system, and another 7 gallons in the front.
The applicator ring changes what percentage mix you want for the siding and roofs. It’s a precision measuring system and is always going to give you exactly what it’s intended to do.
It also holds a 7 gallon post rinse tank for places you want to rinse and neutralize after applying the SH mix.
