Hi Ed, I like what I see, but a thought occurs to me. There are those that take a hard line about 'altering' chips, going so far as to suggest that cleaning a chip is wrong.

Is there any alteration of the chip, at all, or is it simply the removal of dirt? I note one other response asking about taking a layer of clay.

Would this cleaner take off a cancellation stamp (which would be an alteration in my mind), would taking out a burn be a repair?

I don't want to suggest that using the cleaner is wrong, I am interested in getting some, however How far does the stuff go.

I do like the pictures so everybody can see the results.
