You will need a pair of gloves, some sort of non-corrosive cleaner, and non-abrasive microfiber cloth to do this job. In case there is hard to remove dirt and oil on the exhaust trims, you can use a degreaser. After cleaning the tips with water and a cleaner mixture, you can apply the degreaser to remove tough dirt. Wipe away the degreaser with the microfibre cloth. Finally, if you want to add a little more shine to it, you can use a metal polish with a clean cloth. After leaving the polish on for a few hours, buff it off. Doing this often will preserve your exhaust tip’s brand-new look.
