Looking to start a house/mobile home softwashing business.I have read about it but need your help getting started. What chems to use,how to apply it and rinse it off? Have read where some use a pump up sprayer others use a chem tank with a pump mounted on there truck. The other question is do I bid this just like any other house wash job,the $1 lin.foot method.I see doing the s/w method there still brushing some areas.Seems to me if your chems are right you should'd have to.So how much extra should I charge? How do you do 2 story homes?That's all for now hope you can help me out,want to get going as soon a the weather brakes.Thanks,Tim
