hey guys, just wanted to introduce myself on here. Name is Kris, just literally in the process of starting a traditional external cleaning business, offering, Windows, gutters/fascias, conservatories and solar panels. Used to work for someone a few years back using WFP system, but as I'm starting myself I've chosen the traditional method just now. I have a quick question if you don't mind. I understand the benefits of the "pure" water used with WFP but wondered if this is also worth while when using traditional? I know that by adding detergents to the water I will also add contaminants, but plan on using Ecover to minimise this. Just wondered about your thoughts on it. As I'm just starting out I want to make sure the windows that I get to do are as clean as they can be to keep the custom.
