Sticky switches problem on the K3

Hi,

I've had my K3 since April and am about at 8000 actuations.

I've noticed the past couple of weeks that the lever to turn the k3 has gotten harder to switch on.. so it's no longer a snug pull to turn on, but I have to apply more pressure than I expect, so much so that it pulls all the way over to the right most hand position.

I've also noticed that the buttons on the back, the 4 direction button, seems somewhat "sticky" as well.

I don't think I messed with my camera with sticky fingers, but I'm not sure.

Has anyone else had this problem, or no of a way to clean the buttons/lever areas if it was a sticky fingers problem?

The camera is fully functional now, its just I surely don't want the issue to get any worse.

Any recommendations?

Hhmmm..... I had the same problem on a PnS once. Specifically the four navigation buttons. A few drops of lighter fluid per button worked like a charm. I did exercise the buttons some before lighter fluid very rapidly evaporated. If the source of the stickiness is something sugary then an alcohol would likely be a better bet. Isopropyl, vodka? To the best of my knowledge the lighter fluid or alcohols should do no damage to plastics or metals.

Ummmm...you know those Facebook posts suggesting Coca Cola for all manner of unusual cleaning tasks? Well, I don't think it is very good for cameras.

Just kidding!

It may be that there was an accidental exposure to soda pop or some other sticky liquid at some point that you were not informed of. You might want to try a little judicious dabbing at the affected areas with a damp cloth to see if you can wick out the sticky stuff. I don't know if I would use lighter fluid. It is a great non-polar solvent and is useful for flushing the clockwork on mechanical shutters as well as cleaning out degraded film camera seals, but it is likely to penetrate or degrade the seals on your still-in-warranty K-3.

No no no...

Rinse slowly under hand warm water. No chemicals! The seals don't like chemicals but they like water. I had a grain of sand or something that made the front dial hard to turn so I rinsed it while turning. As good as new after.

Oh! That is a good point. The PnS I cleaned up is most certainly not weather sealed. Water a better idea for K3.

Hi all, thanks for the tips.

I've just tried running water over the concerned switches etc.. and certainly, the 4 direction is much improved, or even resolved back to it's original "feel". The on/off switch is much improved, so I can turn it on with a bit less force so it doesn't go all the way over, and will remain at the on position.

So, I'll try the on/off switch again tomorrow, but am certainly feeling better about it... so thanks all!!!
