Hey guys I run a window cleaning service and we handle gutters and pressure washing as add ons but would like to push more pressure washing as a bigger ticket. I live in a very dry city so no real organics on the homes expect dirt bugs and oxidization. Looking for which products and equipment I should be using and any technical knowledge on using the chemicals , mixing etc

Currently we have a 4gpm Yamaha pw4040
