To clean or not to clean? Will cleaning this sign impact value?
I think I like it as is. I like the old look to it, however want to protect it if needed. I'm not sure what the rule is on cleaning tin signs and if cleaning it and some sort of protection is needed. If so what? Have no clue. Like I said this is my first sign. I just don't want to hurt the value by cleaning and in the same token am I hurting future value by not cleaning it and putting something on it to protect it?
