Now if your exhaust is particularly dirty, we’d advise using our APC (All Purpose Cleaner) to remove the bulk of the carbon and build up. Simply spray it onto the affected area, leave it briefly to start breaking down the contaminants before removing with a clean microfibre. Repeat steps 1 through 5 until the entire surface has been polished. If your surface does not have an even coat or does not shine as previously hoped, consider adding a second layer.
