This is the final chapter on my 1994 Bottle Green Prairie Bag #9954 (the one with the fuzzy strap):

Though she was pretty clean inside, I did find a few stray chocolate sprinkles (!) amid the usual purse stuff which I cleaned out with a dry toothbrush. Then the usual warm Dawn bath, good rinse and stuff to dry. The edges of the strap and the padded area around the turnlock needed touching up so I made a mixture of dark green (tube), black and a little tiny bit of red (yes, red) bottled acrylic. Got a pretty good match. When the paint was dry she got Leather CPR 2X, finished with Blackrocks 2X and buffed with a horsehair blend brush. She just glows!
Earlier this year my hubby and I moved his Mom from her house into independent living...a significant downsizing. I found a bottle of Tarni-shield (made by 3M) under her kitchen sink that says it not only polishes, but prevents tarnishing. YAY! Recently gave it a try on the hangtag chain on my black Stewardess, and again on this one, and Im really pleased with the results. Its not nearly as chemically-smelling as Brasso and seemed to work faster. Time will tell about the tarnish prevention

The other brass on this bag was in fairly good patina-ed condition, so I left it alone. Someday I will get out the dremel (also from my MIL) and have a buffing party!
