    Autofocus problem with Nikon N90s

    My new-to-me N90s was acting poorly in AF mode.Wouldn't lock on target and seemed to be having an electrical issue.Did a search on the web and found that dirty camera contacts may be the root of the problem.Cleaned both camera and my AF lenses with a wee bit of ethanol on a Q-tip and the AF is now working.
    A further search turned up a product named "DeoxIT" that does a superior job of cleaning electrical contacts.Does anyone know of a good source for this product?I'm thinking local because it would be cheaper as my photography budget has been negated by the need for a roof replacement on the house.Ugh!!

    I have an F80, I got fed up with missing some shots because the focus would 'hunt'. So I switched off the AF and now focus manually.

    The contacts are gold plated so alcohol such as IPA or ethanol should be as good as anything else, as they're in a fairly "clean" environment in the camera/under the cap I doubt you'll even need to clean them again.

    Not local, but good service and selection:

    Plain Deoxit will clean it up. The Deoxit Gold prevents/minimizes future oxidation.

    No! Don't waste a good India Pale Ale on cleaning contacts.

    (Funny that that was the first thing I thought of with that - the second thought, isopropyl alcohol, will work quite well for this application .

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?
