Prop cleaning and maintenance

[cylon]

Any advice on cleaning or preserving props without damage? Plastic or wood materials should be easy to clean but resin or other type of materials are more difficult. I have most props in display cases but some not. Do you clean or wash props?

I don't recommend cleaning or washing them as I'd hate to devalue them (even if the value is purely sentimental); I personally cover mine to prevent dust from accumulating, whether it be by glass/acrylic display cases, garment bags, or just zip lock bags, and hope for the best.
