I gave the boiler a hot vinegar bath and let it soak about 20 min, then rinse with hot tap water several times down to cool water...the inside of boiler looks MUCH better now with nothing sticking on the walls that looks like it may come loose.
I think this kit may have been on the shelf a couple years and there was some tarnish on the brass, I broke out my new tube of Autosol and in 1 min she was shine like a new penny! I could bring it up more but most of the boiler is hiding under the hood and this will not be a shelf queen but more frequent driver.
