Cleaning fibre glass clean

[grabla]

New Woodford trailer, three months parked outside it's like a stripey zebra. What cleaning products should I use to keep it clean and streak free?

I think I've sussed it out. Raided the 'under the sink' bin of cleaning products and used a strong detergent and it's removed 95% of the water marks. I've just waxed and sealed the surface to help it resist more marks.
What it needs is a gutter to take all the water away, to stop it from running down the sides. I'll do some googling and see what I can find.

The JennyChem range of cleaners for motorhomes are ideal, and best of all not much effort. As im guessing your trailers nice and new it'll pretty much just wash off and be streak free. Can't remember the names of the cleaners I used from them, but theres a cleaner and sort of shiny wash stuff iirc. Cuts elbow grease to near zero

Try applying a ceramic coating Graham.
Will offer stronger and longer lasting hydrophobicity than wax.

GTechniqs offering is good.
