I never anodized in the first place :( But even some of the commercial
anodized fittings had corrosion on them from the water. I tried the
Klean-Strip with manual agitation for about 10 minutes followed by some
light sanding and it got most of the corrosion off. So I'd call it a
success for now.

*Onderwerp:*[AR] Removing aluminum corrosion
I forgot to empty the water out of some my aluminum parts after a cold test and
now there is white/gray corrosion on portions of the parts. A stainless steel
wire brush worked for the areas I could get to but I was thinking of using a
chemical etch to get to the inaccessible areas. MIL-C-38834 is recommended but
it's just 35-45% phosphoric acid and deionized water. Klean-Strip Phosphoric
Prep and Etch appears to be readily available. Any suggestions? Also, what
does light corrosion do to the heat transfer properties of aluminum? Do I even
need to bother?Thanks,-Bob
