I just recently purchased a 2000
Coach Willis. I could use some help/consultation with its restoration. The purse had some verdigris on the metal. Here are the steps I took...
1) Removed Turnlock Hardware/Straps (No verdigris on the straps)
2) Applied Vinegar to the leather areas that had verdigris. There was some verdigris on the handle leather as well. Applied until no more verdigris was removed/no more green coloration.
3) Rinsed out the purse in water
4) Brushed the purse with woolite
5) Rinsed out the purse and dried it out with a blow drier.
6) Cleaned the brass turnlock parts with brasso
7) Applied a metal sheen coat to protect the metal hardware
Anything I else I should do? The color of the purse is fine, the leather looks and feels refreshed, I'm just concerned about the return of verdigris. I'm also very concerned about the verdigris spreading to mine or my fiancé's other purses

. I even vacuumed the area I worked in and then brushed it down with a wet towel. Are there other precautions I should take to prevent the spread?
One thing I know I'm doing next time. I'm buying distilled water....lots of it.....
Also, I asked for help with a Regina in British tan that had a black ring around the turnlock. I'm happy to say that it is barely noticeable (after several months of love/conditioning/washing). Thank you for all your help with it (I think Ledobe and a couple others). It still seems to pick up stains very easily even after applying leather CPR, Blackrock, and finally Obenauf's Heavy Duty LP. Any tips on how to protect it?
Thank you in advanced for any help you can provide ^^.
