Re: Problems with decomposing/sticky rubber on Canon gear

Any pale residue on lens rubber I've had has always come off rubbing with alcohol solution and cotton wool, though it tends to leave the rubber slightly shiny after.

I read some people think it's the mineral oil softener in the plastic leaching out, some think it is reacting with skin minerals in sweat.

Somebody else has recommended some rubber "nourisher" for car parts on it?

In my experience the whitening of rubber is different from the stickiness problem. I really hope manufacturers use different materials nowadays.
