Camera lenses require maintenance to keep them performing at their best, and you'll eventually have to clean your camera lens to remove any grime, dust, particles or debris that are hindering your view. However, since overcleaning increases the risk of damage, you want to be careful about when to clean your lens.

digiDirect has put together a step-by-step guide on how to clean your camera lenses. Read on to gather all the information about knowing when it’s time to clean your lenses, general rules to bear in mind and step-by-step cleaning instructions. We’ve also added some do's and don’ts so you can be confident that your camera’s condition will be improved, not worsened.


Maintaining your lenses by cleaning when required will extend your gear’s life

General Cleaning Rules

When you first get your camera, it’s easy to become a little obsessed with keeping it clean. Most camera lenses are durable, and obsessive cleaning can actually cause more harm than good. The last thing you want to do is damage your camera or your lens because you were too zealous. These three simple rules ensure that you'll be able to clean your camera when it really needs it, and not get into the habit of overcleaning.

Rule One: Avoid Unnecessary Lens Cleaning

Generally, glass is very hard and durable. However, when you start to add layers of chemicals and other advanced coatings to the lens, you're adding things that can scratch relatively easily. The goal is to keep your filters and lenses free of dirt, oil and debris, which you can do by restricting your cleaning routine.

When you store your camera gear in your bag or on a shelf, using the front and rear lens caps at all times will keep dust and grime away. However, your gear will still get dirty once you take it out and start using it. You should occasionally clean your camera bag itself, otherwise dust and grime can accumulate and transfer to your camera's lens. Keeping on top of this can cut down the number of times you need to clean the lens itself.

Rule Two: Accept that Dust Happens

Dust is everywhere, and it will eventually work its way inside your camera lens. Camera lens manufacturers go to great lengths to have a dust-free environment, but they can’t help it slipping through the barriers from time-to-time. If you set your lens on a shelf for a few months, it'll eventually collect a thick layer of dust. In turn, this can produce quality issues with your photographs. However, just a few specs of dust on or inside your camera's lens will have no impact on your image quality.

Keep this in mind when you’re tempted to overclean your lens to remove small specs of dust, as you could end up scratching the lens itself.

Rule Three: Don’t Forget the Rear Element

It’s easy to focus on the front element of your lens (the glass section that you cover with your lens cap), but don’t forget about the rear element. The rear element is not visible when you’re using your camera so it’s easy to forget about, but dirt and dust there can affect your image quality and even transfer dust to your sensor.

Perform a Dirt Test

If you think your lens might need a clean but you’re not totally sure, you can perform a quick dirt test. In just four easy steps, you'll know whether you need to clean your lens or if you can leave it alone a little longer.

  1. Set Your Focus to Infinity and increase your aperture - First, set your camera to Manual Mode and set focus to infinity. Then set your aperture to a high f-stop, like f/16 or f/22. Using these settings will make it easier to identify dust marks when looking through the viewfinder or reviewing your images for dust marks.
  2. Take a Photograph of a Plain Surface - Search for a plain surface that has no patterns or obstacles and take a photograph of it. Ideally, you want to have a light and dark-coloured plain surface for two different shots. This will highlight any dust or dirt that may be lurking.
  3. Examine Your Photographs - Once you take a photo of a light-coloured and a dark-coloured surface, check the images for hazy spots or dust spots. Ideally you will do this by reviewing the images on your computer, but in a pinch you cna set your camera to Playback Mode and zoom in closely on both images. If you see dust marks, cleaning is in order. If not, resist the temptation to clean.
  4. Double Check for Other Dirty Camera Signs - Take a close look at your camera's rear element for any smudges or dust and then look inside your lens for mould. If you find mould – or even just traces of it - you may want to take your camera to a professional and have them clean it for you to ensure that they safely remove it all. 


Using your camera in dusty environments means you’ll need to clean your gear more regularly

Cleaning Your Camera Lens - A Step by Step Guide

Once you’re sure that your camera lens needs a clean, it’s time to get started. Buying a full lens cleaning kit is the first step (here are some recommendations). Don’t worry, they are quite inexpensive. Make sure your kit includes the following products:

  • Lens blower
  • Lens brush
  • Cleaning tissue, pre-moistened wipes or a cloth
  • Cleaning fluid
  • Carbon sponge (optional)

Once you have these items out, you're ready to start cleaning your lens. The goal is to remove the grime without imparting any damage to the glass. This process can take time and patience to do correctly, but we've laid out a step-by-step guide to make it easy.

Step One - Use the Lens Blower to Remove Loose Debris

Using a lens blower should always be the first step in removing any dust, dirt or debris from the lens. This is the safest method as it’s highly unlikely to cause any additional damage. You may find that this is the only step you need to follow.

Gently blow on and around the lens using the blower.

DO: 

  • Use your lens blower as a first resort
  • Give your lens blower a few puffs before you put it to the lens to ensure it's clean
  • Hold the blower very close to the lens, without touching it, to prevent blowing additional debris onto the glass
  • Blow a few puffs of air across the surface of the lens

DON'T:

  • Blow on your lens with your mouth to avoid getting saliva or other particles on it
  • Use air compressors which can drip onto the lens
  • Buy a tiny lens blower to save money. You’ll most likely need a larger one to get the job done to a satisfactory standard
  • Use Freon-powdered air cans to clean it because they cause condensation build-up 


The first step is always to use a lens blower to remove surface dust and grit

Step Two: Use a Lens Brush to Get Rid of Grime

If there are things that won't come off with your lens blower, it's time to move on and use your lens brush. You can get lens brushes in several different materials, but camel hair is popular because it's thick but soft to prevent damage. Make sure you don't touch the bristles before you use the brush because oils can transfer to your lens and be difficult to get off.  

DO:

  • Get a brush with very fine and soft bristles to prevent scratching 
  • Gently brush across the surface of the lens. 
  • Cap your brush when not in use to prevent contamination of the bristles

DON'T:

  • Jam the brush's bristles into your lens or around the camera. Not only can this scratch it, but it can also damage the bristles
  • Touch the bristles with your fingers or you risk the transfer of oil


Step Three: Use Cleaning Solutions

There are two ways you can clean your camera's lens. You can use a carbon sponge, though you should ensure you only clean the lens crystal with it. The more common option is to use a spray bottle of cleaning fluid and a microfibre cloth or cleaning tissue. You’ll find alcohol-based cleaners work well; simply get rid of streaks by applying a second coating of cleaning fluid and gently wiping.

DO:

  • Use a cleaning fluid or spray made with denatured alcohol
  • Use dust-free tissues or microfibre cloths to wipe the excess cleaning fluid away
  • Spray your cleaning fluid onto your cloth or tissue before applying it to the lens

DON'T:

  • Spray your cleaning solution right onto your glass, as this can cause it to seep through the lens
  • Use a cleaning fluid that is simple a combination of water and detergent, or you’ll find this makes your lens appear even dirtier


Step Four: Wipe Down the Lens

The final step is to wipe down your camera lens to get rid of any excess moisture or grime. You have a few options for this step and the one you choose really depends on personal preference. You could opt for single-use lens cleaning tissues, a microfibre cloth or pre-moistened lens cleaning wipes. 

DO:

  • Start wiping at the centre of the lens and wipe in a circular motion
  • Store your microfibre cloth in a bag, so it doesn't get contaminated

DON'T:

  • Grab any tissue laying around to wipe your lens' surface, or you risk scratches and other problems
  • Wash your cloth with fabric softener because this can cause streaking


Many photographers keep a microfibre cloth in their camera bag for quick cleaning on the fly


Step Five: Wipe Down the Lens Cap

It doesn't make sense to go through the entire process of cleaning your camera lens only to put a dirty lens cap back on. You want to double check around the lip of the lens cap for any stuck debris and gently blow it out with your lens blower. Once you remove the larger debris, take a wipe and clean down the sides, centre and outer layer of the lens cap before putting it back on your front element.

DO:

  • Wipe down the lens cap every time you clean the lens itself
  • Treat your lens cap with the same amount of care as you do your lens

DON'T:

  • Put a dirty or grimy lens cap back on your clean lens or front element
  • Forget to wipe out the outer layer as well as the lip and centre


Step Six: Clean the Camera's Rear Element

The rear element is the small glass portion at the back of the lens that is set inside the camera when the lens is attached. Although it generally doesn’t get too dirty, dust can fall on it when you change your lenses. This grime most likely won't show up on your pictures, but it can get into your sensor, so it’s best to take care of it if necessary. Holding the rear element with the bottom of the lens facing down, give it a quick once-over with your blower. Finish with a quick wipe with your microfibre cloth or wipe.

DO:

  • Look for grime before you start cleaning it because the rear element doesn’t require cleaning as frequently the front of your lens
  • Hold it with the lens facing downward to prevent additional dust contaminating it

DON'T

  • Touch the rear element itself because the oil from your fingers can cause smudges that can impact your image quality
  • Forget to wipe the outside of the rear element as well as the lens

 

Step Seven: Clean the Camera's Outer Edge of the Lens

Now that you have cleaned the camera's front and rear elements and lens mounts, it's time to give the outside of your camera a quick check-up. You can give it a brush with your soft-bristled brush to get rid of any obvious debris. Then, apply a thorough wipe down with your microfibre cloth or damp towel. During this process, don’t forget to inspect your camera for any loose parts.

DO:

  • Routinely wipe down your camera's outer case between lens cleanings
  • Use a damp towel to pick up any missed debris

DON'T:

  • Ignore any pieces or parts you see that are loose. It’s important to take care of this straight away, as prevention is easier and cheaper than replacement
  • Skip cleaning your camera's body after every use
