Cleaning a car on location

[PhantomPH]

I've had a search but found nothing, so apologies if this is an eye-roller.

My car will be being used in a photoshoot at some point in the next few weeks (exact time triggered by weather/sky/environment conditions to get the right effect), but of course that means that I never know when I need to clean the car - not withstanding the fact that by the time I get to any location, it's probably going to be grubby again!

The finish does not have to be showroom perfect, but can anyone recommend the best way to clean the car on location? Is there a spray product and some microfibre cloths I should be picking up, for example?

I don't want to trash my paintwork, so will obviously be careful - any suggestions?

Cheers!

Good tips, thanks gents - I washed/polished/waxed the car using Autoglym products a week ago so I will have to try and time it again so it's as fresh as it can be, so the Autoglym rapid detailer could be a should.

Will Google the last product mentioned above and maybe combine that with a water spray for any thick bits of grub that build up.

Thanks all - that's given me a few things to look at, for sure!
