1) Do not use any detergents. NONE.
2) Turn off the plate warming and drying cycles. The heating elements in
the washer can distort or damage plastics.
3) Remove soon after cycle is complete. Do not let items sit overnight.
Shake off water.
4) Stand up or hang to dry.
5) Let items dry inside the house for several days. I usually don't touch
washed items for at least 3-4 days.
6) Don't plug the item in to power of any form until step #5 has completed.
For delicate items, I use water from the sink at a low flow rate, and spray
a mixture of 409 and water onto the item and allow it to soak for a few
minutes before rinsing. I may use a soft paintbrush to clean stubborn dirt
if necessary. Rinse and repeat.
Of course, don't wash the boards with your regular load of plates and
pots..... : )
I also would consider the qaulity of the water. I would wash in
distilled
water. The last thing you want is clorine or other acids and junk from
the
water slower eating your PCB.
