Does anyone recommend going to a pressure washing seminar before getting started?

That sounds like good advise friend. I’ll definitely use that. It pretty well goes with my nature/character anyway, humility that is. I would like to see some some setups and see some chemicals used , learn the most productive methods , buy the right equipment to start with and not waste time. Only thing is the ones that are local are not up to date and really not interested in helping a potential competitor. Thanks for your reply !
