Unfortunately, when new members come to the forums, their posts are delayed and then may be missed as I fear this one has been.
Personally, I tend to try and do as little as possible to these blades. Active rust may be removed with the edge of a copper coin and I have found that very, very fine steel wool moistened with light oil will also do some cleaning of wootz without too much brightening or loss of patination. A few coats of microcrystalline wax, ocassionally refreshed, will then protect the blade and allow reasonable handling.
I have never ventured into experimenting with the light etch followed by restaining advocated by some.
