Hey Steve,
How long and at what temp? I would worry about getting
water in the IF cans etc. Does it just bake out? ?
Thanks,
Bob K6GGO
I will repeat the method used at Hewlett-Packard many
years ago. First step was to remove anything that could be
damaged by water or heat. All closed compartments were
opened. Then the chassis was rinsed with warm water from a
hose. Then sprayed with a paint spray gun filled with a
solution of water and dishwashing detergent and also brushed
if necessary with a bottle brush. After washing it was again
rinsed off with the hose and warm water. Then blown out with
compressed air to remove as much water as possible. Then it
was baked in a thermostatically controlled electric oven at
about 130F for at least 48 hours. I preferred to keep stuff
in there for a week if it was available. Then whatever was
removed was replaced and the instrument checked on a metered
variac. This procedure took off pretty much anything other
than serious fungus (that stuff went to the factory and I
don't know what they did with it).
