Hi Mike:

We have restored over fifty SR-2000/SR-400/SR-400A transceivers and the only 
thing used was Windex on a rag not sprayed directly into anything.  If 
Windex won't remove the crud, you have a problem.  If the chassis is pitted, 
it has been in a very bad place and other components have been abused.  If 
your intention is to do a full restore including a cosmetic rework, think 
twice if it is pitted.

The use of a power washer is a good way to create a parts rig.

Kindest regards Jim K9AXN

I purchased an SR-400/PS-500 at a local estate sale but it is in need of 
restoration. The undersides are quite pristine but both top chassis are very 
dusty and full of grime (luckily no smoke smell). I first plan to dust it 
with a dry brush followed by compressed air as mentioned on the Hali site. 
I've also read about the use of Windex, 409, soap and brasso but this could 
be quite labor instensive. I didn't find anything on using a power washer 
(on low to medium pressure). I've cringe at using water on vintage 
electronics but recall folks drying these boat anchors in an oven. Does 
anyone have any suggestions if this approach is advised? My electric power 
washer has a small tank where I can mix in "cleaner" to the water flow. Any 
ideas on what type of cleaner to use? What about compressed air drying 
instead of oven baking? A good friend of mine and fellow member suggested 
covering the IF cans before spraying with water (sounds like good advice). 
Thanks in advance. Mike WB6UTW
