Hi EM Guys,
I'm new to the world of EM Tech and have been cleaning some score reels recently.
While this comparison looked good to my untrained eyes, the use of an abrasive to clean the board brought up some discussion in a recent restore thread of mine.

Basically, should an abrasive be used to clean EM circuit boards or not? I tried a clean pad and found this...
...what looks to be a copper-y residue, likely taking off some of the traces. A product called "Brasso" was recommended to me. I haven't tried it yet. I'm curious if any of you more experienced EM Techs have any experience/preference with your cleaning methods/products.
- Is there any risk of fire with using a chemical like Brasso?
- Is there a big risk of destroying the circuit boards with an abrasive like green Scotch Brite pads?
- ...and what do you use?
I'm just trying to learn as I go and do the right thing by the machine I'm working on.
Thanks for your time,
Ryan Claytor
