Had my car three days and it's a bit dirty. Is there anything you can use to give it a quick clean over without washing it or anything? I have a Halfords nearby but didn't know what to look for?
Safest option really is to use a jetwash to get a majority of the dirt off the car.
There are some waterless car wash products out there but I certainly wouldn't trust them. The only one I've seen used that appears to be safe to your paint is Optimum No Rinse.
