Between this and the thread that rhm put together about removing anodizing from rims, I was able to successfully de-anodize two rims recently. The first rim was a bit of a challenge because I didn't have a strong enough solution, but for the second rim, I used Rooto Drain Cleaner with Lye that I bought from Amazon. It was about $10 including shipping for 2 lbs of crystals. This stuff worked supremely well and I stripped a rim of anodizing in under an hour. I'll soon be posting the finished rims in a thread... They look quite nice.

I'm with you Tom, thanks DD for this informative thread. Good stuff!
