Whoa, careful there hoss! Maybe surf around for 10 hours or so on every PW site you can find. Read the posts until your eyes start to water. Then ask questions, and read some more.
If you take your time, educate yourself, then hopefully you won't discover how difficult- not easy, it can be.
That way, maybe you won't get a call from your customer saying that you have damaged their siding, blew out the seals on their windows, spotted them, killed their grass and plants, and got overspray on their neighbor's house- and they would both like you to stop by later to ask you who your insurance carrier is. You do have insurance coverage, right?
And- bleach and soap are chemicals. Used in the right way- very effective- used / mixed wrong- very dangerous.
Good luck to you. Start surfing!
