Things to know before underwater camera maintenance
The purpose of the underwater camera maintenance process is always the same: making sure if the seals are damage-free and getting rid of dirt and foreign objects around the opening. But there are some differences depending on your camera type. Therefore, before moving on to the ‘what and how to do’ steps, clarify what is the difference between a waterproof camera and camera with underwater housing.
Underwater camera types
When you decide to start a journey in underwater photography, first you need to get something to take photos with. Depending on your needs and budget, you have two options. Buying a camera that is waterproof without any additional case or using a normal non-waterproof digital camera with extra underwater housing.
Waterproof camera: can be used on land and underwater too without any additional housing up to a specified depth. So they are not just splash- and rainproof, but completely submersible like Olympus TG-6. Snorkeling cameras are usually waterproof up to 33ft (10m) but some models even up to 100 ft (30m) like Nikon W300 model. To know these limits, always check the depth rate in the user manual. Waterproof cameras are popular among snorkelers thanks to its compact size and easy operation. They usually feature pre-programmed underwater mode that helps to get sharp, clear images with balanced colors even for beginner photographers.
If you want to know what models we recommend for snorkeling, read through our best waterproof cameras post. Should you look for an easy-to-use, simple version that even children can operate, see here the top kids underwater camera recommendations.
- top-rated professional underwater compact camera
- 12MP high-speed image sensor
- 4K UHD video resolution
- GPS, temperature sensor, manometer and compass
- waterproof up to 15m/50 ft, shockproof, dustproof
Digital camera with underwater housing: normal non-waterproof camera that is submersible with an extra underwater housing. Diving cases usually can be taken up to 130 ft (40m) or some models even up to 195 ft (60m) deep. A sturdy housing provides a better protection underwater although this is a more expensive solution. A good underwater camera housing usually cost nearly the same as the camera itself (not mentioning accessories like lens ports and lightnings). For this reason, dive housings are mainly used by underwater photographers who shoot with DSLR models. When purchasing an underwater housing, check if it will fit 100% to your camera. Buy original products from your camera’s manufacturer or from trusted diving case manufacturers like Fantasea or Ikelite.
Smartphone with waterproof case: due to dramatic smartphone developments in the past few years, smartphone underwater photography is gaining ground too. Therefore, we thought it is useful to talk a little about smartphone waterproof cases too. Should you use your iPhone or Android device underwater, don’t forget one thing! Although the latest models are advertised as waterproof, it is not true. In fact, they are only water-resistant and this refers to fresh water only! Saltwater can damage the sensitive electronics and erode metal parts, moreover salt particles might block the mic and speaker. The normal warranty doesn’t cover damages caused by saltwater! If you want to use your iPhone while snorkeling or diving, buy an iPhone waterproof case! A good quality case costs almost nothing comparing to the value of latest iPhone models. Samsung waterproof cases are also available! Our underwater camera maintenance tips apply for smartphone – waterproof phone case combinations too!
Checklist before using your camera in water
Visual check-up is a crucial part of underwater camera maintenance that has to be part of your daily routine. The purpose is to make sure that the battery door closes perfectly, sealing is dirt and damage-free. In case of any damage, tear on sealing, crack on the housing, don’t take the camera underwater!
Follow this 3-steps checklist every time before taking your camera underwater to minimize the risk of water damage:
- Check if the sealing is clean! Any foreign objects, even dust or hair can cause leaking. To clean off fine sand and salt parts, you can use a lint free cloth, mini brush, air blower cleaner, or cotton swab. Most waterproof cameras usually have only one opening door at the battery, and this is where you can insert the memory card too. If you have a model with more doors like a separate media card slot door, clean and check the seals one-by-one.
- Make sure that the locking system works perfectly! Once you are ready with the cleaning, close the door while paying attention if it locks well. If you use an underwater housing, you have examine the O-rings too and check if all buttons function.
- Submerge the camera slowly underwater! If everything is alright after the visual check-up, you can enter the water slowly. Never jump with your photo equipment in your hand! Immerse the camera and ensure there is no leaking. You might experience small bubbling, but that’s normal, since air will escape from the mic/speaker. This should last only for a few seconds. If air escapes around the battery chamber door or other openings, remove the camera immediately from the water and dry it.
Camera cleaning after snorkeling/diving
After an enjoyable snorkeling session or dive, you need to clean the camera or the underwater house as soon as possible. Use fresh water only and avoid soap and detergents. Never wipe it before rinsing, because salt and sand parts can scratch the lens! If possible, fill a bucket with water and immerse the camera, otherwise rinse it thoroughly. Press the power button in order to clean the sealing around it. Don’t open the battery cover of the underwater case if still wet. Dry it completely with a clean, soft microfiber towel or cloth. Never let it dry with water droplets on it because stain will build on the lens!
Once it is dry and clean, you can open the battery compartment (or the underwater case) to remove the battery and memory card. Clean off any foreign objects like sand, salt, hair etc. from the seals. You can leave the battery door open while charging, but if the humidity is high, better to place a packet of silica gel inside and close the battery cover door. Like this, the silica will absorb the moisture (see more about this below in the Camera Lens fogging part).

Underwater camera maintenance tools
When purchasing a new waterproof camera, big brands often include some basic underwater camera maintenance items in the package. These complimentary kits can include a cleaning cloth, mini brush or even silicone grease. Don’t worry if you didn’t get them. These tiny but useful underwater camera maintenance accessories can be purchased online just for a few bucks. Moreover, always keep fitting spare O-rings with you just in case! Don’t let a damaged seal ruin your holiday!
See here a few useful underwater camera maintenance tools that we recommend to purchase:
- Professional camera cleaning kit
- Microfiber cleaning cloth
- Silicon grease to lubricate O-rings
- Silica packs
- Camera cleaning brush / Lens pen
- Mini screwdriver kit
Camera lens fogging
It is avVery common problem in hot, humid and windy environments. Camera lens fogging caused by significant changes in temperature resulting condensation on the inner side of the lens.
Lens fogging happens when:
- camera temperature is too high and you put it suddenly underwater
- you moved the camera from cold area (air-conditioned room) to a warm area
- camera side door/battery compartment was opened in a high-humidity room, sealing keeps moisture in
Once the lens fogged up, the only thing you can do, wait until the temperature inside and outside equalizes and the condensation disappears. Usually it happens within 10 minutes if underwater. If the lens fogged up on land, leave the camera in a shady room, open the battery compartment and let it dry out. If condensation is on the inner side of your underwater housing, just simply remove the camera and dry it with a clean cloth.
Tips to prevent camera lens fogging
We know how annoying is if the best shots of your snorkeling holiday came out blurry because of a foggy lens… But luckily there are some easy tricks to prevent camera lens fogging!
- First of all, don’t leave setting up your underwater photo equipment for the last seconds. Prepare it always in advance to let equalize the temperature.
- Use Silica packs! These tiny desiccant packs are mainly used by divers who regularly place them in the underwater camera housing, but they are useful for waterproof cameras too. While charging your battery, put a pack of silica gel inside the camera and close the battery door. It will absorb the moisture so your lens won’t fog up. Remove it before placing back the battery. Good to keep with you GoPro anti-fog inserts! These thin moisture removing inserts can be easily placed in any housing system!
- While preparing yourself for snorkeling or diving, leave your camera in the shade never in direct sunlight.
- Don’t turn the camera lens towards the wind. Strong wind can cool down the lens in seconds resulting instant fogging.
- reusable anti-fog insert for GoPro camera
- can be used with all GoPro and also with other underwater cameras housings
- high-quality silica gel to absorb humidity
Camera water damage
Water, particularly salty water causes irreversible corrosion on the sensitive electronics. Corrosion and rusting build up gradually on metal parts killing the internal circuitry slowly, so errors might occur after some time only. Sadly, serious water damage rarely can be repaired. Therefore, we recommend following these underwater camera maintenance tips to minimize the risk of camera water damage.
Always double check that the seals are good and the door closes perfectly before putting the device in the water! If using a new underwater housing or fresh O-rings, the best is testing the diving case empty by putting only a dry tissue inside. Submerge it to see if the paper gets wet. If not, then the sealing is good and the housing is safe to use.
What to do in case of camera water damage?
If you experience any sign of leaking, immediately remove the camera from the water and turn off the power. Less time in the water means better chance to avoid damage. Dry it with a clean towel, remove the memory card (if the camera would die, at least you save your memories) and the battery. Never try to dry it with hairdryer as heat might damage the plastic and rubber components causing more problems. If you have silica packs with you, put the camera in a bag of silica packets so it can absorb the water. A DIY solution is using rice. Close all openings of the camera and put it in a seal-able plastic bag filled with uncooked rice. It works as a desiccant!
If you are lucky and the amount of water that get into the device was small, the camera will work again. But as mentioned, saltwater is extremely damaging on fine electronics. Therefore the best is sending the device to an underwater camera service department.
How to store your underwater camera?
The underwater camera maintenance doesn’t end when your holiday finishes! It is also important how you handle your equipment when returning home from a short or long beach vacation. These tips will sure help you to store your camera when not in use:
- clean it thoroughly. After weeks of use, the best is to soak the camera in a bucket of water for a longer time (30-60 mins). Like this, you can remove sand and salt particles that got stuck in the tiny gaps. For cleaning, use only fresh water and a lint-free cloth. Never apply chemicals, alcohol or anti-fog spray as they could damage the seals.
- dry it completely. Wipe off all droplet using a microfiber cloth until no water stain spots remain on it. Make sure that all the openings, seals, and O-rings are totally free of water.
- store it in a dry, ventilated place at room temperature. Don’t leave it for long periods over 104°F (40°C) or below 14°F (-10°C).
- it is OK to leave the battery in the camera for a week or two, but if you’re not planning to use it for a longer period, remove it.
- if you use an underwater housing, you need to lubricate the O-rings periodically to keep them from drying out. Also, it is good to put a little silicone grease on the O-rings a few days before your holiday. Silicone helps the O-rings to form a perfect seal. The process is very simple! Just put a tiny droplet of silicone grease between your index finger and thumb finger. Pull the O-ring until it becomes coated with silicone. Use only special underwater camera silicone grease for O-rings! Other lubes like paraffin based ones and vaseline can damage them.
- dive housings should be stored unlocked to keep the O-ring from being compressed for long periods.
- don’t forget about your official maintenance schedule! We are sure you love your equipment and take underwater camera maintenance seriously, but there are things you cannot investigate yourself. In order to preserve the waterproof feature (and warranty too if so), leave your camera in a certified service center to check the device and change the seals if necessary.
