Hi I'm new

Hi my name is Bill and I have painted for many years on and off. I have recently purchased a power washer 2750p.s.i. @ 3g.p.m. for residential cleaning. I will be practicing on my home probably tommorrow. As I am very new to this career I was wondering about everything from chemicals to use ( bleach, TSP, or stuff in containers like ZEP)for vinyl siding, extension wands - any good?, what to use for gutter grime, and what about spores on siding.
I couldn't be any newer at this and I am delighted to see a forum to which I can turn to for insight.
Thank you for all who respond.

welcome and good luck to you
