Ang.:Re: [Test Equipment Design & Construction] Non technical question about the coating on a HP 400E

 

I have done this a couple of times.
First I wash with warm water and soap (sulfo)
Then clear it with alcohol?
When completely dry, I covered it with talcum powder?
Then brushed it away with a soft brush and compressed air. (Gently)

I have had some success on other items with a strong solution of sodium bicarbonate which is readily available for cooking purposes. I apply it with a rag allowing a little time for it to penetrate.? There are usually some surfaces on HP lids that are out of sight and thus good for experimentation. I am not sure about baking powder which has some added acid.

Something similar happened to my old Nikon D80 camera. I cleaned it with Iso-Propyl Alcohol (IPA). It removed all the stickeyness.
