How to know if a camera lens is dirty

How do you know when it’s time to clean your camera lens? Perform the dirt test. Take the following steps to see if your lens needs a cleaning:

  1. Set your lens to manual and turn the focus ring to infinity.
  2. Take a photo of a plain surface, such as the wall or blue sky.
  3. Look at the photo and inspect it for spots.
  4. Turn off the camera and remove the lens to check the rear for smudges and debris.

If you find spots in the photo or smudges on the rear part of your lens, it’s time to clean it.

It’s best to check before every use to make sure your lens is in great condition. Check ahead of time so you can clean the lens if necessary.

Steps for cleaning camera lens

The following is a simple step-by-step guide to properly and effectively clean a camera lens. Make sure you follow the same steps for the front and rear parts of the lens.

1. Use an air blower to remove dust

The first step to cleaning a camera lens is to use an air blower to remove loose dust and debris.

Avoid blowing on it with your mouth because your saliva and leftover food can damage the coating, lead to condensation or smears.

Also, don’t use compressed air or freon-powered air cans because they can drip oil or damage your lens.

When you’re using the air blower, squeeze it a couple of times before using it on your lens because there may be a small build-up of dust.

Then, hold it as close to the glass as possible when you’re using it. By holding it close, you’ll prevent blowing other particles onto the lens.

Squeeze it three times, and you’re finished with step one.

2. Use a lens brush for a second round of dust removal

The air blower won’t remove all dust and debris. So, use a lens brush when the air blower isn’t sufficient.

A soft-bristled brush prevents your camera lens from getting scratched. Camel and goat hair are the two best options to use.

It also ensures that you’re not touching it with your fingers, which have oil and can leave smudges.

To use a lens brush, gently brush the glass to remove specs and dust. You may not be able to remove everything but remove as much as possible.

3. Add a drop of lens cleaner to a microfiber cloth

The air blower and lens brush remove a lot of dust and smudges. However, it may not get everything. Step three is the key to a spotless camera lens.

Add a drop or two of lens cleaner to a microfiber cloth.

Be sure not to spray or drop the cleaner directly on the lens because it can get into the lens or damage it.

Also, the use of microfiber cloths is essential. Paper towels can scratch your lens and tissues can leave debris.

4. Wipe the lens in a circular motion starting from the outer part

After adding a drop or two of lens cleaner to a microfiber cloth, wipe the camera lens in a circular motion starting from the outer part of the glass.

Be patient and gentle. After a few seconds to a minute, you’ll see that the lens is free of fingerprints, dust, oil, debris, and smudges.

5. Wipe the barrel

Aside from the glass, the barrel of your lens needs some love, too. So, use a clean microfiber cloth to wipe the exterior of the lens.

If there’s dirt or debris that’s stuck, dip the cloth in water and rub it off.

You can also use an old or soft-bristled toothbrush to scrub the dirt off of the lens barrel.

Keeping your camera lens clean

Your lens will get dirty, but you don’t have to deep-clean it all the time. Instead, clean your lens as little as possible.

A little dust won’t ruin your lens or the photo. However, proper maintenance ensures your camera lens remains clean and in good condition.

The following are the best practices for keeping your camera lens clean:

  • Always put the lens cap on before putting away the lens.
  • Store your lenses in a dry, covered, and dust-free place, such as a camera bag or dry cabinet.
  • Avoid touching the glass.

By following the best practices, your lens will remain clean and you’ll prevent it from getting damaged.

Frequently asked questions

How do I remove moisture from a camera lens?

Can I use rubbing alcohol to clean a camera lens?
