At times I got to clean corrosion caused by air from the sea of a board and I was wondering what you use to clean such corrosion? The fancy contact cleaners, PCB cleaners and 98% isopropyl alcohol I have tried before are irritating to especially my eyes and I don't even want to think what all those toxic fumes are doing to my lungs and getting a face respirator with oxygen tanks and all to use each time I want to clean a board is just rediculous. The cleaners and alcohol also leave a residu behind that's very hard to get rid of or make the board look dull and not glossy anymore. There must be something more safer for me and the boards to use?

Re: Cleaning corrosion from boards
I found that cleaning battery terminals in a rechargeable solar garden light with vinegar helped fix a contact problem since the rechargeable battery inside leaked, then I gave them a clean with metho.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

Re: Cleaning corrosion from boards
Vinegar fumes (acetic acid) can be irritating to your airways in high concentrations so if you use a lot ventilate appropriately. Fortunately if it smells too strong then it is probably too strong. I've used it to help clean oxidization but it's no magic "TarnX" type solution, it required scrubbing with a toothbrush, then rinsed with warm water, allowed to dry and/or hit with canned air and a hair dryer. IPA isn't going to do much to corrosion based on my experience.

Re: Cleaning corrosion from boards
Solvents that will leave no residue are Trichlorethane or Trichlorethylene. Thrichlorethane was stop in 1996. These chemicals are toxic to the nervous system. But they are the only ones that will leave no residue. I used these chemicals to clean miniature boards that work at a current of 1 X10 -14 amperes. Most applications do not require the boards be cleaned that well. Isopropyl Alcohol is a relative safe to use in small quantities with out a hood fan. It will turn the board white a little, electrically it should be fine unless you have a circuit that is extremely sensitive to any type of residue left. Of what I have learned is all other cleaners will leave residue except the two I have mentioned above.Last edited by keeney123; 07-13-2015, 11:51 PM.
