So, in my wisdom

, and mostly coz my dad said he'd do it

, I have not booked for the site team to jet wash and clean the outside of the 'van after the winter break.
We are due down there in 3 weeks to open up and my dad has his jet wash at the ready. He also has a broom/mop attachment for for the jet washer.
We'll have to do the decking and the outside of the 'van.
What are everyone's recommendations? Any do's or don'ts? What about cleaning products? What is a massive no no? Is anything 'van specific just a giant rip off and a bit of fairy washing up liquid will be just as good?

Any help would be great as we have only really used water to remove light grime, but not actually clean.
