Cleaning

[rookies]

I've seen several 2nd hand lens at several places but the rubber zoom ring all of them have this white faded Mark.

How this happens as never happen on any my own new lens in the years. Can it been cleaned and restored easily?? If so how pls

Could be the rubber perishing, although you can often get replacements if required. It could also be many other things including cleaning residues. Often can be cleaned off but I would take it as an indication of its age generally.

Didn't realise you'd kept any lenses long enough for this to happen to?!

When I was a canon user as I kept lens upgraded bodies

They're designed to go white on Canon so they match the paintwork...

Noo mine never went white that why I am wondering why some people goes white. Mine was still black when I sold it

Mine was still black when I slid it

Ohh was it painful

I'm still using Canon FD lenses I bought in the early 1980"s and still no sign of ware or perishing to the rubber...

I think it's down to salts from people's sweaty hands (hence why some suffer and others don't). It's simple enough to pop the ring off and rinse it in a bit of water/washing up liquid.

You could try giving it a clean with some diluted multi surface cleaner to remove any oils, etc. I have used Eiszett Gummipflege (which is designed for car seals)with some success to restore rubber grips, though they where not in as bad a condition as you describe. There are a number of rubber/plastic colour restorer products designed for cars on the market which might work as well. Use at one risk, etc of course! (a well used trick/hack in the car industry is peanut butter for restoring colour btw)

I know I have a rather simplistic view of things at times, but If they work ok wouldn't you just be wasting your time and money?

I think it can also be partly where in the world the lens has been used - in warmer climates and humid conditions I've seen it occur more. Hence in darkest dullest freezing England you don't see it so often.

In my part of the world it is common for people to use 'dryboxes' to stop fungus and haze developing. I have one myself - and my lenses have yet to change colour - but I do see some locally that have.
