Question!

I use a Nikon D40 with its original kit lens. I was wondering if i could use a cotton swab with a bit of alcohol on the swab to clean a finger- print smudge that is visible on the lens in sunlight. I have previously used soft-lint free cloths and it hasnt come off.

btw pic unrelated.

use a lenspen

A good chamois-type lens cloth will take care of the vast majority of things like this. If you use any kind of cleaning fluid, use it in conjunction with quality lens paper and make sure it's legit cleaning fluid. Don't go using alcohol unless it's an uncoated lens or you don't care about screwing up your coating. Also, NEVER EVER EVER put cleaning fluid directly on the lens. Put it on the paper, then the paper on the lens.

A Lenspen is fine, too, but may not work for more stubborn stuff.

If its only visible in sunlight, then its the residual etching of the multicoating from the acidic skin oils... not coming off.

I'd suggest you leave a piece of scotch tape stuck on the affected area overnight. Pull it off the next day, and get any leftover grime off the spot... but don't expect the fingerprint to go.

Be wary of putting adhesive on your lens.
Skip this and just try a chamois. If that doesn't work, a small dab (onto the cloth) of isopropyl alcohol would be fine.

NO!!!

Don't listen to this jackass!! moisture from your breath or some decent lens cleaning solution and a microfiber cloth made for lenses. Maybe use Residual Oil Remover available for lenses if it doesn't work.

Bleach and a nail brush or a brass brush works great. Make sure it is a brass brush and not steel as it needs to be the softer brass to make sure you don't harm anything. Works great for me.

I'm unimpressed with either of your efforts. One is as bad as the other. It's like watching a retard arguing with himself in the mirror.

OP: When it comes to marks on lenses you need to be very careful. If you can't trust yourself then pay someone else to do it. Applying normal household solvents is risky as with lenses and filters you can damage coatings. What the limits of tolerance are for cleaning solutions and abrasives vary for different models and brands. If you don't know what you are doing or can't find the right information or products, get someone who does know to clean it.

Of course you could ignore this advice and try the classic remedy of attaching it to a lathe and buffing the front element smooth with emery cloth and pouring vodka (maybe with a mixer) to finish off. After that you'd probably be going for the duct tape on the sensor cleaning method.

My fault for not ignoring him in the first place. Hangovers make me crabby.

What's the normal kit lens with the D40? If it's one with a plastic front element, it warrants even greater care in cleaning than it otherwise would. But then, if it's really only visible in direct sun, it's not doing anything to harm photos being taken with the lens anyway.

i'm rude and crude when it comes to my cameras, they are built stronger than you think. This includes the coating on the lenses, they dont make lenses to become damaged when cleaning them.

Front elements are quite tough, i just give it a good lick with my tongue and a wipe with a hankie. rear elements are a different story, I just a bottle of cokin lens cleaner, with my finger and wipe it around then use a clean hankie to wipe it off. Been doing this for 15 years and never fails.

Are they tasty? Would you recommend using some sort of additional condiment for the beginner to this method?

use cigarette paper, it works wonders.

just make sure you weren't drinking milk or something oily before hand. And they taste somewhat glassy.

PROTIP: Using saliva on your lenses to clean them can also help reduce condensation buildup when shooting in humid and weird weather conditions.
