Cleaning and maintaining your digital camera
A clean camera works better and lasts longer. Most damage comes from dust, moisture, sand and careless handling rather than from normal use. A short routine after each shoot, and a longer check every few months, will keep your equipment in good shape.
Clean the outside regularly
Wipe the body with a soft, dry microfibre cloth after shooting, especially after dusty or wet conditions. Use a slightly damp cloth for fingerprints and salt spray, and dry the camera straight away. Avoid household cleaners and solvents, which can damage paint, rubber grips and seals.
Clean the lens with care
Start by blowing loose dust off the front element with a blower brush or a bulb blower. Brush gently with a lens brush if needed. For fingerprints, use a microfibre cloth with a small amount of lens cleaning solution, applied to the cloth rather than the lens. Clean in small circular strokes from the centre outwards, and avoid pressing hard.
Protect the sensor
The sensor is the most delicate part of a digital camera. Change lenses in a clean, dry place, and keep the camera pointed downwards when you swap them, so dust falls away from the sensor. Many cameras have a sensor-cleaning mode that shakes dust off the sensor. Use it sparingly, and follow the manual.
If dust remains on the sensor, a professional service is the safest option. Avoid touching the sensor with swabs unless you are confident and have the right tools, as a mistake can scratch it.
Dust control on location
Dust is worst at the beach, on dirt roads and in building work. Keep the camera in a sealed bag when you are not shooting, and avoid changing lenses outdoors in windy conditions. A lens cap or a protective filter on the front of the lens reduces the amount of dust and spray that reaches the glass.
Look after the battery and memory cards
Store batteries at a moderate charge if you will not use the camera for some time, and keep the contacts clean. Clean the gold contacts on memory cards gently with a dry cloth if they look dirty, and use a card reader that is in good condition. Format cards in the camera rather than on a computer, and keep backups of important images.
Store the camera properly
Keep the camera in a cool, dry place away from direct sunlight. In humid conditions, a sealed bag with silica gel packs helps prevent moisture and mould, especially on lenses. Take the battery out if you will store the camera for several months.
Humidity and moisture in Singapore
Singapore’s humidity is high all year, so moisture is one of the main risks for camera equipment. Store cameras and lenses in a dry cabinet or a sealed container with fresh silica gel, and replace or recharge the gel regularly. Let a camera acclimatise gradually when you come in from air conditioning, so condensation does not form on the lens or inside the body.
Keep the camera dry and cool
Moisture is a common cause of problems. If the camera gets wet, switch it off, remove the battery and card, and let it dry naturally in a warm, ventilated area. Do not use a hair dryer or a heater, and do not switch it on until it is completely dry.
A simple maintenance routine
After each shoot, wipe the body and check the lens. Once a month, inspect the battery contacts, memory card slots and cables. Every few months, check the sensor for dust with a test shot at a small aperture, and arrange a professional clean if you see spots.
