A while ago I got a dark brown NYC basic bag from Poshmark. Thought to post the rehab experience to show NYC bag is totally dunk able. The leather of bag was in good condition other than out of shape, but both shoulder strap and wrist strap were very dry and stiff, they were thin leather and dried out easier compare with the thick leather of bag. First I wiped down the whole bag with cleaning towel, the conditioned them twice with leather cpr in 2 days. Then dunk the whole bag with the hair shampoo I figured might be good for cleaning leather (I did try the shampoo on a testing bag prior with good result). The biggest concern was to conserve the precious creed, I had a Legacy Patricia's creed almost disappeared on me after dunking and drying, then a court bag's creed faded quite a bit. The soft thick glove tanned leather soaked up water like sponge, take a long time to dry, and I was foolish to not to pay attention. So with this basic bag, I dried the interior pocket with creed stamped on really good with towel after dunking, and pulled it outside while drying, the result was very good. She Is almost done and beautiful already.
Love the basic bag. Yours is looking amazing!
