I have my first house wash tomorrow and have played around with my downstreamer for concrete but never a house wash. I tried to calculate my ratio's but end up getting bored trying to figure it out and quit. i have a pressure pro 8gpm @3000 psi hot water unit from bob and 150 ft of hose and the downstreamer is 20:1 from what ive been told. This might be a rookie question but thats what i am and i want to learn, so what is a good housewash mix to run with that setup? i dont need a really hot mix because this house is mostly dust with very little mold. I was told by bob but don't quote me is to run straight 12.5% and if my calculations are correct it comes out to be like .6% strength hitting the house.
thanks for you input i really appreciate it.
