I have a unit in the workshop but haven’t had a chance to test it.
The conservation department at the Museum of Fine Arts in Boston uses
the unit in some of their cases containing precious metal. Intercept
also carries tarnish protection strips which I recommend.
Jeffrey- I’ve heard the old adage that there are certain woods that
are used for furniture and or cabinets that will tarnish silver
faster. If I recall someone once told me that Oak was a culprit.
