How to Clean Your Digital Camera Lens , Filters and Accessories

In this tip , I will be showing you how to , and how not to clean your digital camera lens and accessories. It's recommended that you clean your lens manually as little as possible. I say this because you risk scratching or damaging the coatings on your lens.

What you need
2 toothpicks
Trumpet Oil (musical instrument store)
2 cotton swabs
1 microfiber cloth
1 synthetic fiber brush
95% alcohol (lower percentage not recommended)
10 min of your time

#1 Go out and buy some microfiber cloths. They are available from most big stores at about $1-$1.50 each.
#2 Cut your cloth into smaller sections (about the size of a cigarette box) and save the rest for another cleaning.

Using the brush , very gentry brush the lens making sure to do the edges as this is where dust will be coming from after you cleaned the lens.
Now , simply wipe the cloth over your lens to remove most smudges , fingerprints or other debris from your lens. Do this in a circular motion and do not put pressure on your lens. The camera should be off with the lens in the camera when doing this (compact camera) or the lens must be placed on a soft surface (removable lens camera). Do not use a towel and be very careful with a cotton t-shirt as you may scratch the lens.

#3 Now , use the toothpicks to clean the threads where your accessories are screwed on. Do this by sticking the point of the toothpick into the beginning of the thread at an angle and following the thread as far as possible. This will help prevent that a filter or lens gets stuck on your camera.

What I also like to do is dip a toothpick in Trumpet oil (available at instrument stores) and then repeating the step. This will ensure easy removal of accessories and the oil won't leave a sticky residue. Do not use cooking or other oils. Test the strength of the toothpick before using it to ensure it won't break off during the cleaning. Some people use steel pins , but I find it damages the threads causing metal scrapings to jam in the threads.

#4 If you find that there is a stubborn smudge or substance on the lens that did not dissipate after wiping it down , do the following. Take a cotton tip and slightly wet the one side with 95% or higher alcohol , not rubbing alcohol. Rub this on the spot on your lens.

Now pull the cotton on the other side loose from the tip and gently dry the area which you just cleaned. Wipe down the whole lens again with the microfiber cloth.

Do not use rubbing / other alcohol under 95% as this will leave a residue either due to lubricants (in rubbing alcohol) or due to impurities.

#5 Now that your lens is clean , use the microfiber cloth and the brush to clean you filter cases and lens caps to ensure that the lens won't be dirtied by them. A hand blower is also useful in getting dust out of tight spaces in your lens caps.

I found this instructional video on you-tube , which is also a nice how to guide to cleaning a lens. Just remember to get 95% or higher alchol and not rubbing alcohol.

how do i replace lense cover on a canon sx170 is?

Since I cannot see your pieces, I can recommend actual replacement. You can Google your camera's make/model with replace lens cover and pick from the listings. You can also go straight to Canon USA and search their store as they have replacement lens covers. I did this here for another customer as an example.

My Nikon D 90 works sometimes flawlessly, then sometimes after I have been shooting for about 15 minutes, it just stops working. It turns on but when you depress the button the "F" just flashes with blanks and it will not complete a take - if you depress the button all the way, it just does nothing. This seems to happen more when the battery shows 2 or 1 of 3 bars. I am just starting a professional business taking photos and this is a horrible time for this to happen.

The camera and lens are not communicating. There can be a number of causes - in both the camera and lens. The best way to troubleshoot this is to use another lens. If you get the 'F--" from both lenses, the problem is in the body. If you only get the problem with the 18-105, then the problem is in the lens. The problem in the body is usually caused by impact cracking the lead free soldering of the contact unit to the flexible circuit. This is a major repair and I would recommend you go to a professional repair service.

The problem in the lens can also be caused by impact (check for looseness of the mount), the ground pin being stuck down (metal pin in lens mount that is spring loaded), dirty contacts (spillage or water damage), or damage to the contact flex from impact damage to the mount.

Try cleaning the lens contacts with an eraser, or use methal alcohol on a q-tip. always put solvents on the q-tip, never on the camera or lens. Also lightly clean the contacts in the camera's mount.

This camera and lens are plastic and are easily damaged by even minor impact. Impact can be caused by striking the camera against a door frame or table or cabinet when carrying it on a strap - you may not even realize you have done it.

outdoor pictures show white spot, like ghost

I Would check the sensor to see if it needs cleaning. This will involve locking the mirror up and cleaning the sensor with a special cleaning pad with some cleaning solution. If you are not sure what to do I would recommend taking it to a camera shop as if you scratch the sensor it could be an expensive job. Also check the front and rear lens elements for dirt and clean with a lens cloth or lens tissue. Do not use your shirt as again damage can be done to these delicate surfaces.

tried to clean lens now pictures are blurry

If you're very lucky, you can repair the damage with proper lens cleaning fluid, which you should be able to get from any good camera store (along with lens cleaning tissue). If you're unlucky, or simply not very lucky, the alcohol ate away some of the lens coating. Or perhaps the Q-tip scratched the lens.

In the future keep alcohol and Q-tips away from your lenses.
