removing anodizing from frame

[joseph whitney]

I remember seeing a thread about removing anodizing from a frame.
Any help?
Also, why did S&W make a 6906 when they already had a 669? Other than the sights I can see no difference.

Anno can be removed with oven cleaner but requires a lot of polishing afterward. Assuming you are talking aluminum. Not sure how it works on stainless or other metals.

anodizing

Thank you for your comment, I will give it a try.

Having dealt with anodized aluminum parts in the process of restoring cars, I'd like to offer a word of caution.
In my experience, anodized parts should be stripped/refinished by experts in shops that do anodizing. The anodizing is a chemical process analogous to bluing on steel, but the bare aluminum is much more fragile and chemically active than bare steel. In fact, bare aluminum will react like an old cheap storm door, turning black and pitting very quickly.
Caustic chemicals like oven cleaner, drano, and fertilizer damage the aluminum by chemically combining with it and removing metal from the piece.

I have stripped and refinished aluminum for years with this method. Quality aluminum takes years if not decades to corrode like you are saying. Aluminum oxidizes quickly but will only oxidize on the surface. It will get a milky white color which is easily removed with decent polish. Polish also acts as barrier and keeps the oxidizing from happening. When using oven cleaner use gloves and a scotch brite to remove the anno. Polish with a power ball and some mothers and you will be good to go.

I remember stripping the frame on a Model 39-2 using Drano. It worked but didn't come off like I wanted it to. The oven cleaner is next. I will try a spot under the grips and see what it does.
Thanks for all the reponse. By the way, I took the above mentioned frame to a replating shop that does anodizing and he couldn"t get the
finish off after many tries.
