Can run it thru roof washing rig (delvan 5850 with 65 gallon tank) or down stream thru pressure washer. Have never done any house washing other than pressure washing. But there is lots of mildew on this vinal.
Yeah just run it through your pump from your tank one gal sh and a little dawn for surfactant spray it leave it for 5min and come back it's gone rinse. always wet down first.
yes 1 to 2 gallons is good keep all windows rinsed really well. for houses i mostly use the same system i use for the roof apply the house wash mix then a good rinse with the pressure washer i use the x-jet to rinse some times i use the xjet in a 5 gal bucket but i really just like the ROOF WASH SYSTEM.
