Maybe you'll be able to save it. So, let's begin.
It is important at every moment
First of all, immediately turn off the camera, remove the batteries, accumulators. Clean all accessible parts, using cotton swabs, and in inaccessible places use a rubber bulb to blow out water. The memory card is also removed. If possible, remove and small as a wristwatch, a battery that supports the camera's settings (example pictured).
If the removable lens - take it off, try to shake out the water from all possible places. When shaked out, wipe the optics of the camera, then clean it as usual.
Do not put back any items, put them on a towel to dry under a table lamp. Wrap the camera into tee-shirt, leaving a small opening. Then put the resulting bundle under a desk lamp to the other parts. This significantly reduces the drying time. For a complete evaporation of moisture may be necessary for one to five days.
For speedy absorption of moisture the camera can be put into the material, which has good water absorption. If you do not have special pellets (they are usually placed in shoe boxes), you can put your favorite camera into a dry rice. This is a universal method for any recessed devices.
Do not use alcohol-based substances. Your camera - this fragile offspring of modern technology, produced from plastic and polymers. This is especially true of optics. Do not too expensive cameras is substantially free glass. Even if the lens is a hundred percent glass, it may be coated with an anti-reflective, or some other coating that will be diluted by the alcohol and leave permanent stains. It is better to buy a special cloth for lenses - microfiber.
The most dangerous thing - it is sea water
The most severe cases - photographic equipment is drowning in sea water, brines and various mineral water, slightly less dangerous syrups, liqueurs.
If one of these fluids got in your camera - rinse it. Do not rub, namely, wash it with fresh water, otherwise all will become rusty.
Turn on the camera for a short time to check it on working capacity. If the camera turned on - you're in luck, nothing bad happened. Then we would be advised to turn off the camera and take it to the shop for cleaning and checking for the presence of oxidised.
Take care of your equipment!
