Hi everyone. I was wondering if you could help a first timer clean her camera correctly. I have a Nikon D60 and I am ashamed to say I have never cleaned it in the few years I've owned it :cuckoo:. I have a cheap filter on the front of the lens to keep the actual lens from getting scratched but now I'm wondering if the cheap glass is compromising the image quality. I ordered Giottos Rocket Blower and am waiting for it to arrive. I've heard a lot about Pec Pads and Eclipse cleaning solution to clean the sensor with; would you recommend something different? I'm confused about sensor brushes as well. I'm also hoping that you can offer some insight as to what exactly a lens pen is and how it differs from a synthetic brush. After I blow the large dust particles off the front of my lens, do I then use the microfiber to polish it? And would a lens pen be better to use as it has the brush on one end and the polisher on the other? And how would you go about cleaning the contacts on the side of the lens? Hope you can help me out! Thanks in advance.
 
Hello :)

The first thing to say that only consider cleaning the sensor if it needs it, chances are that if you have kept the lens on all this time then it won't. To test it take a picture of a blank wall at the highest f number you can - if there are "dust bunnies" everywhere then it could probably do with a clean.

With regards to the lens, firstly yes, take the filter off (have a search of the forum, there are numerous threads on this). Then the gist is that you blow or brush off any large bits of dust that may scratch the lens when you polish it, then you polish it.

You can do this with whatever tools you have, a blower and a lens cloth works well or you can use a lenspen which has a brush and a polisher. I like to use lenspens as I don't trust myself to keep a cloth grit free.

That said, probably the majority of my lens cleaning is done by blowing on it and then using whatever t-shirt I'm wearing (assuming I'm not covered in dust/dirt). The front element on a lens is far tougher than you'd expect and this doesn't do any harm at all.

I only generally use specialist cleaning when I'm indoors and giving my kit a proper clean. On the other hand, some people are really anal about this kind of stuff and wouldn't dream of doing what I do.
 
Ditto on sensor cleaning, while after my recent attempt I was very happy it's not worth the hassle if it's not needed. Shoot a blank wall at f22-f32, ISO100 and that should give you at least a few seconds of exposure to purposely move the camera to get some blur; that should make any spots stand out.

I keep thin filters on 95% of the time, and batter these with whatever I have to hand, have yet to damage one. If I'm cleaning the actual lens I'd start with a brush (Hama to a blower and brush in one that I use here, or the old Giottos rocket) and be a bit more careful with a cleaning cloth. Hama do them for <£5 off of amazon and it comes with a tiny pouch.

I'd avoid tissues of any sort though as they can have fine bits that could scratch the lens. Source is a mate whose wife works in an opticians! T-shirt etc... normally fine but this can sometimes blur things for me. Probably depends how clean and how much powder/conditioner used (ie: not right out of machine?!)

I don't work for Hama, and just a fan :)
 
Hi and welcome to the group



Couple of things to remember, first if cleaning the inside of a camera make sure you hold it face down, next don't even attempt to do it where dust lies ,ie carpets. Best place is the kitchen.

When you say "clean" the camera, do you mean clean the sensor? does it have dust spots on the pictures. I have to say here I don't like Rocket Blowers and wouldn't use one as it can blower settled dust within the camera body onto the sensor.

If you intend to clean the sensor take a look on youtube to see how to do it properly. I do my own and use a " Loupe " to see the sensor properly, without it I wouldn't attempt the job, I also use an Artic Butterfly and recommend it over a blower any day, it attracts dust but static electricity it produces.
As for wet clean and pec wipes they are only necessary with stubborn dirt on the sensor, otherwise no need to use.

Don't ever consider using cotton buds you will wind up with one hell of a problem.
whatever you do allow plenty of time and don't rush

Arghh my answer keeps getting erased by accident. Regardless, thank you all for replying! I am under the influence the cleaning process (for the sensor) should go as follows: air blow the sensor, use a sensor brush or dry swab for remaining dust and THEN use the wet method if said dust is being stubborn.

I'm wondering, which works best: a sensor brush or a dry swab? Is it even ok to dry swab the sensor?

As for the lens mount contacts, I watched a video where someone cleaned these using alcohol and a q-tip. I've been told time and time again to stay away from harsh chemicals. So what should I use instead to clean the contacts?

Thanks for all the help and for being patient with a newbie!

Here's the thread I had on sensor cleaning a short time ago, there is a link it it to a long post on here about it too: http://www.talkphotography.co.uk/forums/showthread.php?t=450866

I did a few blasts with the rocket which didn't help (cleaned the mirror a treat though) and then went to wet swabs, using some green things (can't find them now) off of WEX and some liquid I borrowed from a mate. No idea what it was but it was from ebay and worked for me - I watched youtube too. Main point is do you really need to clean the sensor! If not, I wouldn't bother.

The artic butterly seems to get mixed reviews, I read a few horror stories about touching parts of the inside with it and with the price too decided not to, at this time.
 
And yes, I definitely do need to clean the sensor. I've been shooting a lot lately and noticed the black spots on my pictures in my LCD and when I would upload them to the computer.
 
Thanks for the link jmc! Great posts about cleaning the sensor in there :D Still curious about the sensor brush vs the dry swab though; if a dry swab is even possible.

If they're black spots rather than blury blobs, there's a good chance they're miniscule droplets of oil left over from the manufacturing process. Using some products can smear the droplets all over the sensor as easily as they can remove them. The oil can also contaminate the brush (Arctic Butterfly etc) and may cause the brush to leave smears on the sensor every time the brush is reused. Personally, I would try a wet clean (plenty of products available for this, from pads and bottles of fluid to pre moistened pads and dry ones in a twin pack), followed by a test shot (smallest aperture possible, shutter speed unimportant, subject, an even coloured [light] wall). If smears remain, a SensorKlear pad type cleaner should get rid of them. If the spots are more blobby, the chances are that they're motes of dust - a hurricane/rocket blower should dispose of them (don't use a can of air - the propellant may not do things inside the camera much good and the thermal shock of the cold air could cause problem, ideally in the least dusty room available, a kitchen or bathroom (when the air isn't too humid) is probably the best bet. Some dust is a bit sticky (pollen for example) so a wet clean may be necessary to shift them.

Lenses/filters cleaning? Personally, I use the little one shot lens cleaning tissues and a drop or 2 of Isopropyl Alcohol based cleaning fluid - a bottle lasts years! Microfibre cloths work well too but I'm always a little worried that much reuse could leave a speck of grit in them which may not do a lens/filter much good! On the subject of filters, plain/UV/Skylight ones do very little for digital, apart from adding a negligible amount of protection to the front element (can help keep aiborne debris off the lens - water spray, sand, mud etc) but do nothing to improve the image - cheap ones (and expensive ones to a lesser extent) can degrade the image and introduce flare (if only there was a filter to improve flair!!!) Lens bodies get a once over with a soft brush and if really grubby, a damp cloth.

The electrical contacts rarely need cleaning, if they do, a gentle clean using a slightly abrasive glass fibre brush (available from Maplin) will remove any grubbiness and oxidisation. If cleaning the body's contacts (and, ideally, whenever the throat of the body is open [no lens or body cap fitted]), keep the body facing down so gravity doesn't help dust get inside. Again, a drop of Isopropyl Alcohol on a tissue can be used to remove oils (from greasy fingers) that may be causing connection problems.
 
I did mention getting a "Loupe" for examining the sensor before, to my mind it is one of the most important bits of kit necessary when cleaning a sensor, its like a lit magnifier which sits over the opening



Looking through Loupe at sensor, so easy to see those nasty dust bunnies now if you have any.

:help:

Locked up the mirror and rocket blew the sensor. It didn't help at all. When I take the lens off, I can see visible dust on the mirror (before I lock it up). Proceed with a wet cleaning on the sensor? And how do I clean the mirror?

Here is how it looks when I shoot a white blank page at f/36. It looks way worse than I first thought. Wow... Now I'm really stressed about it.

yes it will... the more glass you put in front of the sensor the lower the image quality.... which makes it an irony that L lens users put cheap UV filters on them!
 


These are the tools I use to clean a sensor and mirror

So what do I do??? it may give some guidance for those wanting to clean their own.

First of all I make sure I am working somewhere there is no dust,ie kitchen, and then allow plenty of time, its a job that needs a bit of care but nothing the average photographer can't tackle themselves. So often I read that a camera is sent away for cleaning as if there is some magic in doing it. Well there isn't and I just can't see any reason for being without a camera for at least a couple of weeks and paying not only for postage but what a company charges for doing it. With the kit in the photo is all you need and the cost occassionally of ordering more fluid (above will last years) and a couple of wiping pads packs

Sometimes its just dust on the lens that needs attention and cleaning them is dead simple so won't do a breakdown of that.

Ok as I have said earlier having a "loupe" (the black round object) makes the job so much easier and I would dare to suggest it is on bit of kit ever photographer should have, I used to do the trick of photographing a white sheet of A4 paper then checking the digital photo of it. Yes it works but does mean having to keep going from taking a photo to checking it as I just mentioned. This method is slow to say the least and I soon gave up on that idea.

So we now have the mirror locked up to check for dust, as you can see I do have a rocket blower but reluctant to use it as it can stir up more dust in the camera body and make matters worse. If intended to use this bit of kit make sure the camera is facing downwards first

So onto using the" loupe" which in reality is just a magnifying glass that has built in lights which is placed over the opening which the lens fits into. With the mirror locked up it is easy to see minute dust particles on the sensor. Dust particles can be from a small hair to light dust to really stuck on bits of dirt and each is generally easily recognisable through a Loupe. Dealing with a small hair or light dust one has a choice of ways to remove it. First is the blower method which I am not keen on and the second method is by using the Artic Butterfly; thats the pen like thing in the picture with a brush on the end. Its different from an ordinary brush as it builds up static electricity because inside there is a small motor which makes it spin. Spinning it for about 5 second builds up enough static to allow the brush to attract any loose dust when gently wiped across the sensor face. After each pass the brush should be removed and again spun to shake off any dust it may have attracted. This method I prefer as it only cleans the sensor and any other loose dust in the camera body remains.

Of course you can buy a pen with a brush one one end and a rubber pad on the other (only costs a few pence) but having tried using it I soon gave up, the brush only moves dust from one side of a sensor to the other and doesn't do anything else. The rubber type other end just leave a mark on the sensor which causes more work to remove it

Ok now for stubborn dirt against just dust and we are starting to talk about wet wipes . Again in the photo you will see special fluids for the job which can easily be obtain on the web. I use two types of wiping instruments, for use of a better word, first is the one that looks like a cotton bud but its not. This I use just to clean a spot not the whole sensor. Just as with using he spade type it only needs a minute drop of fluid on the tip , drenching it will make the sensor harder to dry/clean. The spade type again just a small drop of fluid and with it one wipe in one direction and check the sensor. Here I have read then the wiping blade should be discarded, I tend to ignore that and after checking it for cleanliness use it again with the other side. I just can't see any reason why it can't be used many times providing it is clean and won't scratch the sensor, but that choice is up to the individual of course. Word of caution, don't try and press too hard with whichever dirt cleaning tool used, far better to go over several times than trying to do it in one wipe. Never ever use a cotton bud as an alternative its not designed for the job and WILL
leave small hairs.
Afer each operation just check to see the dust/dirt has gone ,you don't want to clean a sensor that's already clean. Make sure you have a fully charged battery to keep the mirror locked up.

Just a brief note on where other dirt/dust my show up. One is the mirror, easily checked if the dirt shows in the view finder but not on the photo, Cleaning is again easy by using one of the aforementoined wipes and if necessary abit of fluid. I just gently manually lift the mirror to do the underside,jJust treat it like cleaning a sensor. The other placeI have come across is the camera body side of the viewfinder lens, easily found obviously and this may need a bit of a wipe as well but usually needs no attention



Thats really all there is too it, no magic methods, no secret way only known to companies offering this service.

Hope this may be of some help for those wondering if they could do the job themselves, there are plenty of demos on youtube bearing in mind some may vary slightly from how i do it

THANK YOU for the tips! I guess I'm going to have to grin and bear it and just buy the swabs and cleaning fluid as I'm nearly positive I have welded dust. The rocket blower appears to have made things way worse than what it was originally, ARGH :bonk: I also ordered a sensor brush but am doubtful that this will eliminate my problem. So wet swabs, here I come.
 
Hellotiffani

your welcome, as I said for me a "Loupe" is the best bit of kit you can have for sensor cleaning. Yes they are rather expensive as I have at around £75/80 ,but consider that against sending the camera away for cleaning. The cost of professional sensor cleaning is around £55 from one company I found plus cost of postage etc. So should you need to clean a sensor more than once the cost is worth it.

I would agree with professional sensor cleaning. I considered doing my own but didn't. I believe the cost was only £30 for a sensor clean by experts.

It's not worth doing something your not comfortable with, especially if you cause damage costing allot more than a clean.

Try find a local place to save on postage and so you can collect your camera the same day :)
