Re: With what should I clean it, dear Henry, dear Henry? Message #6 Posted by Ed Look on 2 Oct 2003, 12:50 a.m., in response to message #5 by Neil Strickland
Personally, I'd not recommend any chemical agents; I believe that'd cause more problems later.
The best bet might be to gently scrape or gently scour it off with something small, if it is a small area. But I would use a bit of plain water, perhaps on a cotton swab or tiny wad of paper towel to wash off any leaked corrosives. Most of the inorganic salts that form or leaked acids or bases should be fairly easily removed by water. After being sure to rinse thoroughly to forestall any further corrosion, be sure also to DRY THROUGHLY, for the same reason.
I recently had a close call with my old HP-34C: a replacement pack of NiCd cells began to leak and slightly damaged the contacts, but a bit of wiping removed the small amount of leaked and corroded material. Of course, toss the leaked cells. The contents of batteries are toxic and corrosive.
