Anodized finish removal from aluminum
What is the simplest process to remove an anodized finish from aluminum other than sanding it out? Once the finish is removed and buffed to a high luster, what is the best way to protect the shine from corrosion?

The easiest way is to take it to an anodizing or plating shop which can strip it the right way in chromic-phosphoric acid. Second easiest is oven cleaner ⇦this on eBay or Amazon [affil links] , but I would not guarantee that an inexperienced user wouldn't dull, pit, and ruin his parts. (Plus it's dangerous). The way to lock in the shine is to anodize again, although a clear lacquer coating may be good enough.
