Personally I am a fan of a damp microfibre cloth used gently on hard surfaces and a polymer cleaning product such as used on car interiors, plastics or even laminate hard floors to maintain the surface finish/lustre.

*to supercharge a carbonate such as baking soda or magnesium sulphate (used to remove moisture) dry bake in a oven at 160-180 degC for 30minutes or so.
