JJV's Best Aluminum Cleaner
Using a hudson sprayer, spray the bare aluminum from bottom to top. One side at a time. Allow up to 5 minutes for product to soak in, make sure you have even foam spread around. Do not let the product to dry on the aluminum! Then take a pressure washer and rinse well. Wipe dry or allow time to air dry. If you're seeing white chaliking, wipe with a wet towel or power wash more. That is the old oxidation and heavily soiled areas may require repeating.
