Hi
 Wash them in soap and water. It is Ok to use
a brush to loosen hard stuff. Rinse in clean water and shake
off or use a air hose to remove as much water as you can.
Place in an oven, set for 110F. Make sure that there is no
line of sight path to electric heaters. Bake for several
hours and allow to cool slowly.
 Avoid getting water in coils and switches if you can. It
generally doesn't hurt most electronic components.
