I think it would be interesting to find out how it works to clean,and if the fumes will darken light woods such as maple."
My understanding on this is the ammonia gases work on the tannin acid in Oak, which Maple doesn't have. You can however wet the maple with a strong tea solution & dry off just as in whiskering, then place in a closed atmosphere with an open dish of the ammoniaa & leave set. The directions I saw for this called for Strong Ammonia. I did try some small pieces, one a set of pistol grips, in regular household ammonia & it woked well for them. It gave an extremely attractive appearance to a piece of curly maple, really making the curl stand out.
