With open shelves, the models need to be dusted regularly, and occasionally a thorough cleaning with soapy water and a soft cloth - especially after the models have been to a show. I'm convinced the texture/film coating some of the models is from the smoke from BBQ booths near the open doors of the display area.
Some of these models were built in 16 years ago, others just a few months ago.
With every cleaning I break things off, or in the case of some older builds, they tend to 'self destruct' if handled too roughly - plenty of repair work happens as part of the cleaning.
