Sensor, Lens & Body
How to keep every part of your camera in perfect condition - the right tools, the right technique, and what never to do.
Your camera is a precision optical instrument. Dust on the sensor appears as dark spots in every photo. Fingerprints on the lens degrade contrast and sharpness. Grime on the body works its way into buttons and dials. Regular, careful cleaning is not optional - it is part of owning a camera. The good news is that with the right tools and technique, it takes less than ten minutes and costs almost nothing per session.
This guide covers everything: why cleaning matters, what tools to use, step-by-step instructions for every part of the camera, and the mistakes that damage sensors and scratch lenses. We also review four cleaning products available at Carlos.gi - from a comprehensive kit for beginners to a professional sensor cleaning solution.
Why Camera Cleaning Matters
Dust, oil, and moisture are the three enemies of image quality. Sensor dust is the most visible problem - even a single speck of dust on the sensor will appear as a dark blob in photos shot at narrow apertures (f/11 and above). Lens contamination is subtler but equally damaging: fingerprints and smudges scatter light, reducing contrast and creating flare in bright conditions. Body grime is a long-term concern - dirt that works into the camera body can cause buttons to stick and, in extreme cases, reach internal components.
What You Need
Using the wrong tools is the most common cause of camera damage. Never use household cloths, paper towels, or clothing - these scratch optical coatings. Never use compressed air cans on sensors - the propellant can permanently damage the sensor surface. The correct tools are inexpensive and last for years.
| Tool | Used For | Safe On Sensor? |
|---|---|---|
| Rocket blower | Loose dust on sensor & lens | ✓ Yes |
| Lens cleaning fluid | Stubborn smudges on lens glass | ✗ No |
| Microfibre cloth | Lens glass, LCD screen, body | ✗ No |
| Lens brush | Loose dust on lens glass | ✗ No |
| Sensor swabs | Stubborn sensor dust | ✓ Yes (wet method) |
| Lenspen / pen cleaner | LCD screens, lens glass | ✗ No |
How to Clean Each Part
Step 2: Use a lens brush (soft, dedicated) to sweep away any remaining particles.
Step 3: For fingerprints or smudges, apply 1–2 drops of lens cleaning fluid to a microfibre cloth (never directly to the glass). Wipe in a gentle circular motion from centre to edge.
Step 4: Use a dry area of the cloth to buff away any residue.
Step 2: Enable "sensor cleaning mode" (or "mirror lock-up" on DSLRs) in the camera menu to expose the sensor.
Step 3: Use a rocket blower - insert the nozzle just inside the mount opening and squeeze firmly several times. Do not let the blower touch the sensor.
Step 4: For stubborn dust, use a sensor swab with a drop of sensor cleaning fluid. Swipe once across the sensor in a single smooth motion - do not scrub.
Step 2: Use a slightly damp microfibre cloth to wipe the exterior - avoid all ports, buttons, and the mount area.
Step 3: Use a dry cotton swab to clean around buttons and dials where grime accumulates.
Step 4: Clean the lens mount contacts with a dry microfibre cloth - dirty contacts cause autofocus and communication errors.
Step 2: For stubborn marks, use a screen cleaning gel (like the Fersay E-5411) applied to a microfibre cloth.
Step 3: Never press hard on the LCD - modern screens are fragile and can crack under pressure.

Celestron Deluxe Lens Cleaning Kit
Complete 5-Piece Kit · Lens Fluid · Microfibre Cloth · Wipes · Brush · Carry Pouch

The Celestron Deluxe Lens Cleaning Kit is the one product we recommend to every new camera owner. It contains everything needed to clean a lens properly: a bottle of lens cleaning fluid, a microfibre cloth, individual lens wipes, a soft-bristle lens brush, and a carry pouch to keep everything together. At £27, it is the most complete solution available at Carlos.gi and covers all the basics in a single purchase.
The lens fluid is safe for all coated optics and works on filters as well as lens glass. The microfibre cloth is large enough to use properly - many cheaper kits include cloths so small they are practically useless. The individual wipes are ideal for travel when you do not want to carry the full kit. This is a Celestron product, so the quality is consistent with a brand that makes precision optical instruments - you are not buying a generic kit.
RICOH Pentax Image Sensor Cleaning Kit O-ICK1
Professional Sensor Cleaning · Swabs + Fluid · Safe for All Mirrorless & DSLR Sensors

The RICOH Pentax O-ICK1 is the only product in this guide specifically designed for sensor cleaning. It includes sensor swabs sized for APS-C sensors and a bottle of sensor cleaning fluid - the combination needed for the wet-swab method that removes stubborn dust that a rocket blower cannot shift. At £44 (reduced from £49), it is a professional-grade solution from a camera manufacturer that understands exactly what the sensor surface requires.
While the RICOH branding suggests it is for Pentax cameras, the swabs and fluid are compatible with all APS-C sensors regardless of brand - Sony, Canon, Nikon, and Fujifilm mirrorless cameras all benefit from this kit. If you shoot at narrow apertures regularly and notice dust spots in your images, this kit will solve the problem. Sensor cleaning is intimidating the first time, but with the right tools and a steady hand, it is straightforward.
B+W Lenses and Filters Cleaner
Professional Lens Cleaning Fluid · Safe for All Coated Optics · Filters & Lens Glass

B+W is one of the most respected names in optical filtration - the same company that makes the premium B+W filters stocked at Carlos.gi. Their lens and filter cleaning fluid is formulated specifically for coated optical glass, making it safe for multi-coated lenses, UV filters, polarising filters, and ND filters. At £10, it is the most affordable dedicated lens cleaner in the Carlos.gi range and an excellent complement to any microfibre cloth.
Unlike generic cleaning fluids, the B+W formula leaves no residue and evaporates cleanly. It is particularly useful for photographers who use filters regularly - filter glass picks up fingerprints and smudges just as easily as lens glass, and a dedicated fluid makes cleaning quick and safe. If you already own a microfibre cloth and just need a quality fluid to go with it, this is the product to buy.
Lenspen DigiKlear Display Cleaner
Carbon Cleaning Tip · No Liquid Required · LCD Screens, Viewfinders & Displays

The Lenspen DigiKlear is a pen-shaped cleaning tool with a carbon-compound tip that removes fingerprints and smudges from LCD screens without any liquid. One end has a retractable brush for loose dust; the other has the carbon cleaning tip. It is the fastest and most convenient way to clean a camera LCD screen - one or two strokes of the tip removes fingerprints completely, with no streaks and no drying time.
The DigiKlear is also useful for cleaning electronic viewfinders (EVFs) and the small glass eyepiece of optical viewfinders. Its compact size makes it ideal for carrying in a camera bag or jacket pocket. The carbon tip lasts for approximately 500 cleaning cycles before it needs replacing - making this exceptional value over its lifetime. A practical, no-fuss tool that every camera owner should have.
Our Recommendations
"A clean camera is a reliable camera. Ten minutes of maintenance after every shoot protects thousands of pounds of equipment and keeps your images sharp."
For most photographers, the Celestron Deluxe Lens Cleaning Kit is the right starting point - it covers lens, body, and LCD cleaning in a single purchase. Add the RICOH Pentax Sensor Cleaning Kit if you shoot at narrow apertures and notice dust spots. The B+W Lens Cleaner is the best standalone fluid if you already own a cloth. The Lenspen DigiKlear is the fastest way to clean an LCD screen and worth keeping in every camera bag.
