Hi guys just starting in the window cleaning game and I'm about to set my van up for wfp so I thought I would ask you guys if you've got any tips before I start putting everything in the van. I have a Citroen dispatch/500liter tank/pump and controller (on the way) and 19 liter di vessel (on the way) just need to get minibore hose and pole. Any suggestions on anything would be a help thanks
