Email AZ and ask them what they recommend. I'm sure they have a particular product that they use for final polishing before they leave the factory. I know that a couple of high end guitar makers use a product Novus No. 1 for their final polish and would probably work well. Frankly, unless there is a particular residue you need to remove, I believe I would just use a soft cotten cloth slightly dampened with water. Be careful with auto cleaners, as many are slightly abrasive.
