I have used a product call PERK that you can get from your local dry 
cleaners. Tell them what you are using it for because they will not sell it 
to the general public. PERK helps clean the verdigris out of the flange. I 
have actually applied in on a Steinway action, put it out in the sun,  and 
later I find the verdigris oozing out of the flange.

I used this product in the 80's and found the results to be very productive.  
Dropping the entire whippen in a solution gave fantastic results that lasted 
for years. The verdigris does melt away as described. Some centers will have 
to be repinned. This is the result of "verdigal compression". (squished felt)
