In order to remove oxidation from a vehicle's paint, simply use a good polishing compound or cleaning wax. Avoid scuffing up the paint when removing oxidation from a car with help from an ASE-certified mechanic in this free video on auto repair and car maintenance.
Good afternoon my name is Tom Brintzenhofe, Certified Master Mechanic out of Reading, PA and I'm going to talk a little bit about how to remove oxidation from your vehicle's paint. It is not too difficult. You just need yourself a good polishing compound. McGuires makes some cleaning wax which is really awesome for removing oxidation. My preference is polishing compound because it also removes some scratches and whatnot but the easiest thing is just take a little bit you either want it on a slightly damp rag or just a dry rag either one of the two will work fine. Just try to use something that is nice and soft nothing that is going to scuff the paint up. Just work it real nice and slow, don't try doing a big area at once. Keep rubbing this back and forth. It is going to start drying on you but just try and keep ahead of it as much as you can and as you are rubbing just keep on going until you actually rub it away. It is going to take some elbow grease and a little bit of time here. This is where you want to be careful when you are using an orbital sander because I mean an orbital buffer because this is where you are going to end up with your swirl marks but as you see it is starting to cake here on you, that's when you want to stop and flip your rag over and start wiping it off. Sometimes if it doesn't come off immediately just take yourself a wet rag and just go over it a little bit and that will take it off. Get yourself a clean rag and I tend to like these little blue towels. They are pretty soft, they are pretty durable, they don't fall apart on you. Just rub it clean. Just keep in mind that when you are doing this you want to go back over it with a coat of wax because unfortunately that polishing compound or any kind of cleaner will take the wax right off but that's all there is to removing oxidation from your car.
