Hello, I am picking up a set of Ping ISI BeCu Irons this weekend 3-PW. I found them on Craigslist and I am paying $125 for the irons. They are dirty but not hacked up, grooves look new, but they are tarnished to hell. First question is, do you think the price is good. From what I have seen on completed sales on Ebay it looks like I am getting a steal. Not sure if Serial #s match but I will find out Saturday. Second question is I have read differing opinions on the best way to clean them. Everything from Coke, Vinegar & Salt, Ketchup, Tarn - X, Bartenders Friend, Brasso etc, I would like to remove the tarnish and get I nice polish to them. Any ideas are appreciated.
