Lens Cleaning Techniques/Opinions

From Roger's article: "We know breathing on the lens and using the corner of your T-shirt usually works."

Honestly, I do this more often than I care to admit and I've never had a problem. My normal "careful" method is virtually the same, blow off dust and breath vapor on the lens and use a microfiber cloth. If there is a really bad or oily spot, I use lens cleaning fluid with a microfiber cloth. I avoid anything very complicated and I avoid like alcohol or ammonia because I don't want to damage any of the coatings on the filter/lens.

The big key is to avoid rubbing any grit, dirt or sand around on the glass, possibly causing micro scratches!

But in general, I see no reason to go OCD nuts on how you clean lenses. They don't get THAT dirty anyway and I use mine in all kinds of environments. The worst issues are usually finger smudges with dirty fingers that contain oils.

This is also why I buy upper mid-range quality lens filters, they have harder glass and better coatings. That way, I don't have to clean the lens front element very often, if ever.

Good luck!

I just clean the front surface of the filter that is on my lens pretty much all the time. ;D
I agree...I use only the best filters, though.I am a fan of Lenspen and similar products even for my expensive multi coated filters.
1. Use blower for loose dirt
2. Use brush
3. Use cleaning end of the Lenspen with the Carbon-Laden swab
4. Use brush an/or blower if necessary

Works like a charm and no abrasion.
If someone tells you to use "Lens Tissue"...RUN LIKE HELL!!!! 8)

+1, agreed. I like B&H's rule #1. When to clean is probably as important as how to clean.

Yeah...some people will test the autofocus of there lens for weeks, way off the charts obsessively using FoCal etc. and then clean the front of the lens surface off with their tee shirt. LOL! :p

LOL - and I would put good money on the fact that we have people on here who spend more time cleaning, calibrating, and tweaking their gear than they do shooting. Photographers are by no means unique in this department, however.

I start out by wiping the front with a rag and some isopropyl alcohol. I clean the rear by pouring some of the alcohol (if you don't have isopropyl alcohol, a quality Scotch works too) into the back of the lens and shaking it sort of like you might a martini for James Bond. If there's any gunk on the front, I've found a piece of 5,000 grit sandpaper cut into a small disk and mounted on a Dremel or other (I recently moved up to using a Foredom unit) rotary tool mandrel gets it off quickly (note: wetting the sandpaper helps for the next step). If I have to use the sandpaper, I then also use a felt wheel on the rotary tool, usually with a flexible shaft attachment (if you're using a Foredom, it already has this, you only need to buy it for other rotary tools) to help remove any scratch marks. I'll usually use some sort of polishing medium as well, but you have to be sure to keep wiping it off if you use any. To finish removing any scratches I used to use a standard dual wheel buffer, that works - - but - - I've since found that mounting a buffing wheel in between centers on my 24" wood lathe is better since I can pop the wheel into the laundry machine each time. After this you want to remove any dust or dirt the process created, so I use a water pressure cleaner. If you don't have one, you can use a power water jet attachment for your garden hose. You have to dry it after this step. I use a heat gun. When you start to smell the electronics burning a little bit, you know you're almost done, so stop the heat gun then and just let it sit. The residual heat will do the rest.

If you follow the above procedure the last step is to chuck your lens into the trash. :p

Kidding aside, I use a Giottos rocket blower. I don't know what size (does it say somewhere?)? I used to use a Lenspen Original, but I gave it to my father recently because he didn't have anything for his camera. I just ordered the DSLR kit. I'm excited to use the newer ones with the supposedly colorless translucent carbon. I never had any trouble with the black carbon, but I always wondered if the day might come when that changed.

Also I have to agree. My viewfinder gets dirty. My LCD gets dirty. My lens? Not that much.

Hi Mitch.
I just started following your step by step guide, got the Tamnavulin inside the lens, then started reading ahead whilst shaking the lens, this was when I realised that this was supposed to be humorous, :eek: I now have a £1200 cocktail shaker! :'(
Do you think I should pour away the first measure, is the one used to clean the cocktail shaker likely to be contaminated, or will it be safe to drink? No sense wasting fine whisky as well as a lens! ;D ;D ;D

Cheers Graham.
