I will pass along a method of cleaning used at Hewlett-Packard many
years ago. We washed equipment sent in for overhaul using a paint spray
gun filled with warm water and dishwashing detergent. This, along with a
soft brush, would remove most dirt and junk. Once washed the equipment was
rinsed off using a sprayer hose attachment and dried in an electric oven
for several days at about 130F. Remove anything that can be damaged by
moisture, meters for instance. We also found a high rate of failure of
hermetically sealed transformers and chokes. This is counterintuitive but
if the seal is leaky moisture can get in and has a hard time getting out
again despite the baking. I don't know what effect this will have on the
ferrite cores in the SP-600, maybe none.
