Fenicks Caravan Cleaner - magic. (available from Halfords - enough for 40 caravans)
you will rarely get a dirty upvc frame properly clean with tfr and waterfed brush trust me. use a cream cleaner with a none abrasive pad, then rinse and dry, then ad a wax... fantastic resultsrichy
i bought mine from euro chem
yeah, its quite expensive but it will last for years as you hardly use any and it does look fantastic and the customers love it. i think its around 50 notes for 5 litres
