I had this white spotty mold problem with my Scalextric Lister Jaguar which had been stored in various drafty damp garages throughout it's life. In fact the mold was worse on the inside so maybe it fed on oil and dirt! I cleaned it several times over the years but the mold just kept coming back.
Fortunately, a recent strip down, several thorough cleanings with warm soapy water and a nice cosy centrally heated home seems to have cured the problem for now.
