I'd take it to you're local petrol station and use the jet wash on it mate. Dry it. Then proceed on.Help me!!!
I'm due to go down and wax the car tonight but i've just been down there and its got a bit of dust on it. (Its stored in a dirty unit)
I can't wash it because of where it is.
What is the safest way of polishing / waxing it tonight without causing too much swirling.
Otherwise you're just asking for trouble.
