I've looked at the information on the web about Miracle Dry Wash and it looks quite impressive. I was thinking about giving it a try but was hoping that someone on the forum would give you some feedback before I took the plunge.
I purchased this from Marks and Spencer who sell it. It worked fine and left a good shine. Don't think I would use it on a really dirty caravan or car but for giving it a quick clean it is ok.
Thanks for your feedback Andrew. There is no water available where I store my van so I will probably give give it a try before I put the cover on for winter storeage.
I used it on holiday. Can't stand a dirty van for a fortnight and feel guilty using site water so it is ideal and worked a treat. Sad really but that's me.
