p.1 #1 · Cleaning Your 17-40L Glass?

Hello all,
I just recently cleaned my 85mm Lens and found it was very easy to clean the glass however the L Glass is a big question mark ?

Any help would be appreciated !

A little lens cleaning solution on a piece of lens tissue, then wiped gently on a lens that has been blown free of grit has always worked for me.

A Lens Pen or similar is a modern (more expensive) version of the same.

There is nothing different about it. Whatever worked on your 85mm prime will work on the 17-40. When I'm feeling fastidious I use a lens cleaning cloth and a bit of lens cleaning fluid. On other occasions I just breath a bit of moisture on the lens and clean

I clean L glass and other glass the same way:
Some Eclipse fluid on a Pec-Pad. The Eclipse fluid (methanol)
evaporates quickly and leaves no visible residue. Works great for me.
But I seldom clean lenses, since minor dirt spots have no visible effect
on my images.

same as anything else

formula mc on chamois/microfiber cloth works great (the latter way better than lens tissue)

Really? I have found Eclipse to be absolutely terrible with lenses - it evaporates too quick to be useful and leaves strange smears behind. Don't ask me how / why. I have found lens cleaning fluid, which specifically evaporates more slowly, much more useful.

Then again I may be doing something wrong, as most often I'll breathe and use a microfiber cloth

Ideally--semiconductor grade isopropanol and microfiber. (when I bring my lenses into the lab)

Realistically--breath + microfiber.

if its a sealed lens then a quick run thru the dishwasher usually works. Be sure to use the extra sparkly rinse aid though

Oh that's why weather sealing is important!

Once I blow off (lift off very carefully if stuck) any grit or such, a broad tipped lens pen does a super cleaning job. The only drawback is that periodically the lenspen needs to be replaced otherwise it might become an agent of your lens destruction.

If we are talking specifically about the 17-40, you shouldn't have to clean it as, I believe, you should have a UV filter attached, to stop it sucking in dirt and dust when you zoom. Just clean the filter.

Doesn't the 17-40 have the internal elements exposed without a UV filter, since the front element moves up and down as you zoom? I always have a filter on so I don't really care how I clean it. Sometimes use my shirt

Otherwise I blow the dust off first then use lens cleaning solution with a lintless cloth.

Interesting. Well, I admit I have to act quickly before the fluid evaporates, but it seems to work well for me.
I don't have streaking problems with it.

Another good product is Formula MC cleaning fluid. Sold in many camera stores.
You have me curious about the Eclipse now. I think I'll go clean a lens again.
