My camera got wet from the rain a few months ago and I changed the batteries and tryed cleaning the blue batterie acid off but recently when I would go to turn my camera on it doesn't turn on and when it does and I go to take a picture it takes a picture but then turns off. I checked the batteries and there is still a little bit of blue batterie acid there. Do I clean this with baking soda or white vineger?

Replace battery pack but before clean well acid residue

Do you mean your Nikon D80 battery haven't bean used for 4 months and you store it with no power? If so you battery maybe has been't damaged. Over discharge is heavy damage for Li-ion batteries. And when you store it with no power and for a so long time... You need to store it at 40% charger and at a cool but no cold place. Cold and hot are the killers of Li-ion batteries

If you have replaced the starter and the battery is charged, it sounds to me that the problem is the solenoid. The starter solenoid will be in the engine compartment. Open the hood. It will be located on the passenger fender well. It will have red battery cables going to and away from it. There will be a small gauge wire, blue/red that can be jumped. Pull the blue/red wire just enough to where it is connected but to where you can see the bolt that it is connected to. Use a wire to jump across the blue/red connection to the wire on either side of the solenoid. If the vehicle cranks, then the probalem is the solenoid, replace it and it will take care of your problems. Picture below will give you an idea as to what the solenoid looks like.

Your problem may be due to weak/worn out batteries or corrosion on the battery contacts inside the camera which can prevent the full power of the batteries from flowing into the camera. Try this free fix before you do anything else: remove the batteries and wipe the camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sandpaper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and place them back in the camera and give them a full charge (assuming that you are using rechargeable batteries). This cleaning clears the problem about 90% of the time. If it doesn't work for you, it may be time for new batteries, or the camera may have a problem that requires professional repair.

Digital cameras as with any digital equipment is very sensitive to moisture and needs to be kept dry. If this happened recently (within the last 2 days) there could still be hope, remove the batteries and flashmemory card, with a hairdryer on GENTLE heat and from a distance of one foot direct the slightly heated air into the battery compartment for a few minutes, alternate by blowing air gently around the whole casing of the camera. Do not use very hot air as this WILL misform the plastics of the camera. Do this a few times , then charge the batteries again put in memory card and try again.

CHECK BATTERY CABLES,NO CORROSION AND ACID OR BAD GROUNDS TO BE PRESENT. YOU MAY ALSO HAVE A SLOW DRAIN ON ELECTRICAL SYSTEM. IS SOMETHING ALWAYS ON THATS OBVIOUS?

was it ever left in the sun?

Have your supply voltage and frequency checked under load.

You may be lucky because the battery acid may not have gone beyond the contacts in the battery chamber: open battery chamber and clean out especially at the bottom of the chamber and blow out any loose stuff when you finished cleaning ( use pencil erazor or something similar , but do not use sand paper or anything that will damage chrome plating of the contacts ; you do not want corrosion at later stage ).

Replace it a wet damged camera seldom survives
