Cleaning dust and dirt from the lens (inside)

How do you safely clean the optics of a 6100. I can see dust particles on the inside of the lens (looking through the lens at an angle). I cleaned the lens on the outside with a camera lens cloth but don't know how to approach cleaning the lens on the inside. Thanks!

Hi Nutty Prof

You will have to open up the unit by unscrewing the screws at the bottom and taking off the top cover of your PB6100.

Right behind the lens is the Lightengine ( where the dust collects )

Take off the cover of the Lightengine by unscrewing the two screws at the top of it . Then blow out the inside of the light engine with Air in a can ( available from most good PC shops )
and then reassemble.

If the dust particles still show after this ( which I doubt it will ) then you will have to take it to a Service Centre to get cleaned out as you will not be able to reassemble the lens once taken apart - it is a HUGE job !

Thanks for using Fixya and Good Luck !

I need cleaning instructions to remove dust from the inside of my Panasonic Lumix DCM-ZS10 Leica lens


You are going down a dark alley here, these lens are specially coated very high quality optics and very easy to damage if not handled properly. You are taking a big risk with a high dollar item. I would think twice.

Tip

Wireless Optical Mouse Cleaning


Optical Mouse Cleaning is a problem for many. The mouse cursor seems to randomly jumping around and uncontrolable, which is caused by dirt on the optical beam. To prevent this from happening, place a piece of clear scotch tap over the optical lens and it will prevent dirt from getting into the lens. Then you won't have problems caused by dirt.

Cleaning and lubrication


Cleaning a lens should only be done with a non-scratching cloth and tissues designed for optics; moistened with plain water or cleaning solution designed for optics. Use of paper towels, glass cleaners, ammonia, etc. can scratch and strip special optical coatings from lenses. Apply water or solution to cloth or tissue - not to optics.

Do not lubricate lenses. Lubes attract dirt and dust and can seep into the lens and gum up aperture blades and eventually cause them to stick. Nearly all lenses do NOT require lubrication. Lenses should be cleaned professionally when not working correctly.

Good luck!

The eyepiece lenses have something on the inside. Can they be removed for cleaning?


  1. Carefully clean your binoculars by firstly removing any dirt or dust from the main body and straps using a soft microfibre cloth. Avoid the lenses at this point using any form of cloth on the lenses before removing all dirt and dust particles first could destroy them.
  1. Gently remove all traces of grit, dirt or dust particles from the lenses using a soft lens brush or canned air specifically designed for the purpose.
  1. Waterproof binoculars can be rinsed gently under a tap but be sure to use on lightly running water, avoid high pressure water as it could damage your binoculars.
  1. Gently remove any remaining marks using lens cleaning tools such as a lens pen or lens cleaning fluid and lens tissue. Do not be tempted to use kitchen towel or anything else lying around that is slightly rough and may scratch the surface of the lens, only use a lens pen, lens tissue or a lens cloth. Gently wipe the lens using a circular motion working from the centre of the lens to the outer edge. NEVER apply lens cleaning fluid directly onto the glass (always apply to the cloth) and always ensure that the lens cleaning fluid you are using is recommended for the type of lens coatings that have been applied to your binoculars (Do not use general household glass cleaning products or products designed to clean computer screens or glasses. Such products could destroy the lens coatings of your binoculars if used).

There is dust inside the lens. how do I clean the dust from inside the lens?


Your projector needs little maintenance. The only thing you need to do on a regular basis is

to keep the lens clean.

Never remove any parts of the projector except the lamp. Contact your dealer if other parts

need replacing.


Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.

• Use a canister of compressed air to remove dust.

• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner

and gently wipe the lens surface.

Never rub the lens with abrasive materials.

Pentax SMC D 16-45 Lens How to clean inside? Pictures are showing spots and all the outside lens have been cleaned along with the inside of the camera itself. Can not see the spots when taking pics only...


Your lens would need to be absolutely filthy with enormous dirt specks to cause the fault you describe. Dust, fingerprints, and regular minor debris simply doesn't show in the final image. In any case, you cannot clean inside the lens without dismantling it and that is a job for experienced specialists only.

Your fault is a dirty image sensor. You can buy sensor cleaning kits, but if you're inexperienced with them or trying to clean the sensor in a dusty environment you'll just make matters worse. Many camera shops offer sensor cleaning while you wait at relatively low cost. The reason you don't see the dirt when taking the picture is either because you're looking through the optical viewfinder or because the LCD screen simply doesn't magnify the image enough to show the marks which are present in the image.

You can prevent the dirt from reoccurring by never leaving the camera with the lens throat open for more than strictly necessary, and by always trying to keep the open lens throat pointing slightly down when swapping lenses.

I hope that I've helped, please take a moment to rate my answer.

My system don't play the games and movies, what can I do?


First try This turn the PS3 off from the switch at the back of the unit and then turn it back on while holding the eject button.

If that fails theirs blue ray Cleaning disks that be be purchased and they will clean the lens and optics very effectively. sometimes restoring them to working order.

Dust in my Kodak m863 lcd screen


Hold the camera upside down and gently blow off any grit and lose dust particles. Next lightly wipe the lens with a few drops of lens cleaning fluid, place the fluid on the lens cleaning paper, not directly onto the lens and then wipe the lens.

Cleaning the inside lens


To access the inner optics on these compact digital cameras the lens must be disassembled from the inside out. Usually the camera casing has to be removed, boards and connections moved out of the way, and the lens assembly actually removed from the camera. At that point the lens can be taken apart and the inner optics accessed. In other words, yes, this is a job for a professional. It is also probably not worth the cost just for a couple specs of dust. These lenses are not sealed. This is why the dust gets in there to start with. If you get a can of compressed air and carefully blow into the gaps between the lens parts in different directions somtimes you can get enough air through to blow off the inner lenses. This does not often work though. David Millier Advance Camera Repair

Cd player gets "stuck"


Built up dirt particles like dust or smoke on the lense can cause this. Buy a cleaning kit with a disc that has brushes that you dab with a small amount of alcohol which spins in the CD player and cleans the lens.
