Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion Should I clean the Skelly sign I just bought?

Thank you everyone for your advise. I probably used a bit of everyone's. All said and done there are three things I could not have done without: patience, elbow grease and Bartender's friend. Actually four, could not have done without the advise. I Spent the whole day rinsed often, and learned a lot. I have to say, my elbows actually hurt. Any thoughts on the value of a sign in this condition?
Thanks everyone,
Jay
