Fits one of my (many) mottos perfectly:

"Always use the right nasty chemical for the right job".

If it can clean a smokehouse, it oughta be able to clean my garage.

Wow that did a really good job of stripping the anodizing. Did it eat any of the aluminum underneath after it devoured the anodizing?

When I took the anodize off the inside of a tailcap, I used abrasion. I happened to have a small cylindrical grinding wheel that took about 2 minutes to remove the oxide coating. It's probably safer than lye or acid, but certainly not as fast and not as clean-looking. Nevertheless, it does work when that's all ya have. /ubbthreads/images/graemlins/smile.gif

Caustic solutions will attack aluminum, with or without anodizing. if you use a strong alikaline solution, plan on having your part etched. (please wear eye protection) dip for 10-15max seconds (do a test dip for one second) at a time and rinse with water, check and try again. If you leave in solution for several minutes the part will be severely etched.

At the plating shop I almost always used a 13% nitric acid solution to strip anodizing. Not all colors would come off. For problem parts, after the nitric dip (10-30 seconds), a light dip in the caustic cleaning solution took off all remaining colors.

For really critical parts phosphoric acid was used when no etching is required.

This is for information purposes only. Please don't chase down Nitric acid. a 13% solution will desolve copper, most steel and part of your hand.

Re: easiest way to get anondize of inside mag c

While employed at a university library near here many years ago, I found a beaker of yellow liquid on a cart one morning. Since it didn't look like the yellow liquid that most folks would have expected it to be, I checked in with security and the chem squad. Turned out it was a VERY strong concentration of nitric acid.

Apparently, someone got bored and was tossing zinc strips into the acid, inside the library. Can you say chemical AND fire hazard?

And my wife wonders why I don't get too excited about most spills and accidents anymore...
