Chassis Cleaning

[Greg Gore; WA1KBQ]

Also might add:

Get a good powerful shop  vac with the hose and blow nozzle plugged in on 
the blow side and use to quickly  blow rinse water away for a faster dry. A 
couple of hours out in the hot sun  will finish the job. An easel made to 
support the chassis on an incline works  best. I always place chassis on the 
easel with the power transformer at the top  to minimize possibility or water 
intrusion. Tape over IF transformer adjustment  holes and fasten plastic 
baggies around power transformers and chokes with  rubber bands to help keep 
water out. The 50-50 mix of 409 and ammonia in a  plastic sprayer bottle is 
the best cleaning solution you will find. Industrial  409 is much more 
effective than the diluted kitchen counter variety available in  the grocery store. 
Use in combination with water and be extremely  careful around any dials, 
knobs or any painted on witness marks or  nomenclature as this solution is 
very aggressive and will quickly dissolve most  screen printed and painted 
markings. Get a good assortment of brushes;  i.e.: tooth brushes, paint 
brushes, etc. Be sure to tape around the metal bands  of brushes that have them so 
that aluminum parts are not gouged up and scratched  accidentally during the 
cleaning process.
