Hello pwi I'm new to the pressure washing business. I'm afraid as hell I don't want to destroy any property. What kind of chemicals should I need to buy for houses and concrete .I just purchased a big tex trailer double axle 6.5x14 and a 8gpm 3600psi hot water unit. I'm a pretty handy guy what water tank size should I start off with also what hose reel brands and hoses shall I get. I have a 100 ft pressure hose already.
