    Hi. I left my Koi Medic salt meter outside. It got wet. It no longer works. I have tried new batteries.

    There was some rust present on the inside of the plastic but not as far down as the "workings".

    I have cleaned the rust off. It will no longer switch on.

    Can it be saved?

    Always with you it cannot be done...

    Try not.
    Do… or do not.
    There is no try....

    before trying new batteries
    i would have left it to throughly dry in an airing cupboard or in a bag filled with dry rice for a few days....

    Electronic equipment can often be dried out successfully on top of the tank in the airing cupboard especially if you remove the battery cover and give it a good suck every hour or so to suck out the humid air inside and draw in fresh dry air. I've done that several times for customers when equipment has been flooded in plant rooms or dropped in a swimming pool.

    However, if the battery has been left in, electrolysis may have already caused corrosion that may have damaged the tracks on the PCB or the components beyond economic repair.

    If you haven't removed the batteries, take them out now and try the airing cupboard.

    I've been astonished at the things I've revived from a good soaking. Cordless phone left in the garden all weekend in the rain, several sky controls dunked in the bath (got TV in the bathroom in case your wondering!), and mobile phones down toilets, dropped in bath (a real hazzard zone!) and left in a sink of water for 10 mins. That last one was the Galaxy Note 4 I'm typing on now!

    My tried and tested method:

    1. As soon as you retrieve item either turn it off or don't switch it on. This will minimise damage to circuit boards.

    2. Open device, remove batteries. Dismantle into main component parts and wipe off as much water as poss. Give a good shake to get moisture out from inside, then suck any remaining droplets out from every opening with a hoover.

    3. Place in a ziploc bag (or similar) with as many silica gel packs you can find (I actually have rechargeable silica gel packs now for this very purpose!)

    4. Seal bag and place somewhere warm (airing cupboard or window sill in sun). Keep checking. You should see condensation appear inside bag if lots of moisture deep inside. If this happens, open bag slightly to let it breath and not saturate silica.

    5. Be patient. I left my Note 4 in a bag like this for 2 weeks after it had been in water for 10 mins and was totally saturated. It worked the first time I turned it on and it's been fine ever since! Quite miraculous Help me Manky Sankenobi. You're my only hope....

    It would be kind of ironic if electrolysis has killed a salt meter wouldn’t it?

    Thanks all. I have poked a pouch of little bag of that silica stuff in there too.

    It wasn't actually submerged, just left out in the rain on a flat surface.

    The battery compartment has been removed but the batteries are still in the compartment.

    Warm place, and buried ina bowl of dry uncooked rice.
    Have washed land-rover key fobs at 60 degrees . Was told that new car security module and replacement key was necessary. From reliable friend in LR not the lackey .As modern land-rovers can only take 2 key fobs per module. Tried the rice trick as per many mobiles I've taken dingy sailing kayaking by accident(salt)
    Worked fine.
