Cleaning the top of the van

Hi has anyone used 'wet and forget' for cleaning the roof of the van or had any issues with the paint after using this stuff. 
Many thanks
Sam

Yes I have used it and no, I have not had any issues.  
I have also used ProKleen MY16 Patio Cleaner which is similar and which specifically mentions use on caravans and motorhomes.

See my post here:

I find imported east Europeans or Iraqis work best.
£30 get whole van done here, once properly clean it's a lot easier to keep clean.

That's great l appreciate your advice on this.
Cheers

You're lucky you don't have a Peugeot van conversion of around 2009-2012, the paint comes off without any chemicals, just breathe  on it and it flakes off revealing the primer that it failed to  adhere to.
