Alcohol. The medicinal version.

Thanks, Dennis.

Wasn't kidding about the clean finger.  I rub my thump or index finger over the contacts and it has served me well.

 

No chemicals dripping anywhere to worry about.

 

A little grime is easily wiped away for most circumstances.  For heavy duty grime, you can resort to more industrial solutions, I would just use your finger.

I use Deoxit.  The specific product is the Deoxit Gold 100% liquid.  It is specifically for cleaning electrical contacts.  You simply apply a small amount to a swab or lint free cloth.  You should not see a film - just a few drops is enough to remove oxidation and dirt.

 

It is surprising how much wear builds up on the mount and contacts.  While that normally does not damage the gear, it is possible to create some damage and even a need for repair.  A macro image of the mount is helpful to examine the mount and contacts.

Tks Eric,

Just did a google,

Must be what Peter was talking about from Jaycar, they do sell detoxit

 

Also, I have a feeling the AF internals on the 300 f4 may need replacing,

Did make a rattling sound a few days ago but went away, have done some AF fine tuning but results were inconsistent

I use electronics tuner cleaner and finger. It evaporates fast but leaves no residue. Isn't Deoxit tuner cleaner, Eric?

DeOxit is a fast evaporating cleaner specifically for electronic contacts.  It leaves no residue.  It's recommended for camera contacts.  You just apply it with a small swab or Q-tip - not more than a drop or two at a time.  You don't want it wet.  I don't know whether it is a "tuner cleaner" but it is for cables leads and contacts which could apply.

I use a CRC product called, "QD Electronic Contact Cleaner". Have used it for years, dries fast, leaves no residue. Spray it on a soft cloth or QTip. Or as someone else suggested, just plain alcohol.

 A product called Glenfiddich came to mind but found an old bottle of Kodak lens clearer that worked OK,

AF now "appears" to be better, I'm going to try some different focus options with the 300 f4 shooting from the boat, I'm thinking spot may be a better option on an unstable platform,
