HELP - cleaning disaster!

Whilst trying to drip a little lense cleaner fluid onto my 70-300 lense the dropper fell out of the bottle and the entire contents emptied onto the lense.

I quickly grabbed it and turned it upside down to try and reverse the flow of fluid.

The lense has been left to dry for over a week but its dead

Can I get it repaired?

Anything can be repaired but the question is will it be econmic to do so. The only way to determine that is to ask Canon to quote.

For the record it was and is my understanding that lens cleaning fluids should be applied to the cleaning wipe not to the lens and then wiped i.e. the same methodology used to clean the sensor.

Hope you can get it sorted AOK.

Thanks

Yes a newbie error and I found out the hard way. Don't do it anymore.

Just for the record, the word lens only has one "e". The plural form is "lenses".

It sounds repairable but you'd have to send it in to get a price.

Sorry about your lens. Btw, I've been trying out those Zeiss lens wipes and they seem pretty good. I had a mess a couple weeks ago when I went to clean my lens with sold old lens fluid. It left some kind of residue all over the lens. So I picked up a couple new lens cleaners. Some generic stuff from my local bick and mortar shop worked ok but the Zeiss wipes worked the best.

Thanks for the advice on how to handle this lens disaster

I have plenty of this stuff http://www.klearscreen​.com/

Would that be suitable for lens cleaning?

I would not use it. Instead, get some decent lens cleaning fluid from a reputable camera shop.

Here's my lens cleaning procedure:

Quality lens tissue (such as that sold by Kodak), a good lens cleaning fluid, and PROPER TECHNIQUE is the way that I have cleaned my lenses for decades. What is "proper technique"?

First - the goal is to clean the lens (or filter - I would use the very same process) without grinding any dirt/debris into the lens. To me, this absolutely dictates single-use surfaces for anything that touches the lens. That's why I use lens tissues instead of a washable cloth or - particularly - something like a lens pen.

Here are the steps that I use to clean a lens:

1. Use a squeeze-bulb blower to blow any loose dust off the lens. 90% of the time, step #1 is all that is necessary.

2. Take a lens tissue out of the pack. Fold it once, holding only what was the ends of the tissue. You want to be extremely careful to NEVER TOUCH the areas of the lens tissue that will be touching the lens. This will avoid transferring oils from your fingers to the lens.

3. Moisten the folded portion of the lens tissue with a little lens cleaner. You don't want the tissue dripping wet, but it must be damp.

CAUTION: NEVER apply lens cleaner directly to the lens (though it won’t hurt a filter, you don’t want liquid leaking into the lens’ innards).

4. Wipe LIGHTLY across the lens ONCE with the damp tissue. Then either turn it over or fold it so that you can wipe again, but with an unused surface. You can do this as often as needed, as long as you never wipe the lens twice with any surface of the tissue. This prevents scratches. Again, make sure you never touch an area of the tissue that will touch the lens.

5. Ensuring that the lens is actually clean, use a dry tissue, handled the same way as above, to wipe the lens dry. Since you have already removed the dirt, there's no risk of scratching the lens with the dry tissue.

6. Dispose of the used lens tissues in a proper trash receptacle.

That's it in a nutshell. Simple and effective. I've been cleaning my lenses this way for over 40 years, and all of them have pristine glass (and none have ever worn "protective" filters).

Yea I'd stay away from those for your camera lenses. If you visit B&H's website and do a search on lens cleaning it should show you all kinds of fluids, tissues and cloths. Probably any good fluid and kodak lens tissues would work fine. I wanted to try the Zeiss fluid but they were sold out at the time. And pickup a Giotto rocket blower if you don't already have one. It just takes a few bursts to get the surface dust off.

Never put the fluid on the lens itself. Always put the fluid on the tissue or cloth you use to clean the lense. You can fog the lens with your breath first before applying the cleaning cloth to reduce friction and help spread the cleaner.

Nope, "lense" is a valid spelling too.

i use a rocket blower - breath on the lens and wipe it with a Clean Hanky works a treat
