General External Cleaning

[Airboutique]

Don't be shocked but I have never washed my Airstream. Polishing it is not an option at this time but I was wondering if there is any special product I need to use just to wash it ? It seems to be in pretty good shape but I
noticed the appearance of water marks/streaks from the snow melting
off the roof and onto the body. Any suugestions would be greatly
appreciated. Shelly

I used Dawn detergent in a bucket of cold water, a weak dilution, maybe two tablespoons or so.

Then I wash it with a long-handle soft brush and rinse it. Let dry and serve.

It went a lot nicer, shinier and brighter. Didn't take more than a half hour at the most.
