I picked up yet another Korona on eBay because I just can't get enough of the things. It's a bit musty though. The bellows could do with a good hoover and some nourishment and the metal is in need of polishing. What products are best for cleaning metal and making my bellows and wood supple again. Thanks
I found Daly's ProFin a really good product for sprucing up the finish on my old Korona. I cleaned it up with a damp cloth, then put on a coat of the ProFin. It filled in all the little checkered cracks on the ancient varnish and made the whole thing glow. It produces a very hard, durable finish that is easy to touch up. The bellows on mine was so stiff I couldn't use it. I had a new one built.
