Here are the results of my blue Kira rehab. I gave the bag a bath and scrubbed it inside and out. There was some blue bleeding into the bath water, but not bad and luckily the lining is blue. Then I drained, stuffed, and dried the bag and applied Leather CPR. I used acrylic and CPR to repair the rubbing damage but it is still faintly visible in a couple of areas. Finally I did some gentle polishing of the brass hardware.
These are the after pics of my Kira 13930 B4 BL (2009, $898) and I bought some more daffodils to compliment Kira because she is a major bag!
