Personally I would not think of stripping my anodized Reo. The other finishes no problem, but not the anodized. And mucking around with caustic soda is not my idea of fun.dankie
How far do have to strip the Reo?
Anyhow, maybe you have compelling reasons to do so. Imo, you must get all off, inside and outside - leaving some inside might not be visible, but could affect resale value.
