Sticky Grip

Yesterday, I took out a camera from my drybox and discover is now producing sticky stuff. I try cleaning with a wet cloth and to my horror part of the grip broke. Any way to rescue the grip? Also, any idea how the sticky stuff came about and how to prevent it to happen from our camera?

Was the camera a Canon by any chance? Rolling Eyes

Minolta ?

I have seen some so bad they stick to your hand. I have no idea if there is anything that can save them, it must be a fault in the way the plastic was manufactured.

The one mentioned above is a Minolta but both of you are correct my Canon is also starting to show sign of stickiness on the grip. Worst is both are supposed to be top end professional film cameras.

Mine was a Canon EOS5. The grip got so bad my hand stuck to it! I tried all sorts of cleaners but in the end I covered it with black adhesive electricians tape.

This might be a problem of different people having different sweat ?

When I got a bunch of Minolta AF lenses I hadn't got a camera, so at the next camera fair I looked for, and bought a 50001, 7000 & 7000i - all with perfect grips, but I saw a lot with sticky and broken grips. It seems to affect some and not others Question

My hands sweat quite easily and have never noticed any issues on cameras. My cars' steering wheels and gear knobs suffer though.

I had the same with a sigma lens. Nothing would clean the sticky off. I think its decomposing acrylic. Something we think takes thousands of years. The material felt like that stuff that covered the Contax RTS. Porsche design, Zeiss optics, Poundland leather.

A camera technician told me once that a few times he received lenses where the owner's skin PH was so acidic that, when
the lens was touched and not cleaned, the fingers' grease etched the lens coating.

+1 as Orio answered already, yes. 'Normal' sweat pH is slightly acidic. Sweat pH changes depending on diet. Some people, such as those who eat red meats regularly, may have very acidic sweat. Vegetarian sweat is much less acidic.

When I worked in a camera shop I remember seeing a camera with a clear fingerprint on the lens and it would not clean off no matter what we did with it. The repairman said it would have to be re-coated. I think the customer threw it away.

I have a Sigma 50/2.8 Macro which is doing the same. It is leaving black marks in my bag and everywhere, not nice. Can these grips be replaced? Has anyone used alternative materials?
