    yeah i thought the same thing…i didnt like the way that looked.

    You may also apply a thin coat of grease or engine oil on the terminals after the battery dries to prevent future corrosion.

    You know….It would be easier to use a Coke

    Goggles please … You do NOT want to splatter any of this into your eyes. Protect them

    CAUTION: You are using water which almost shorts the two terminals. I would say this is dangerous and can cause current to flow between the two terminals. What I would suggest is pour little water on one terminal at a time and then clean the other. Or even better remove the terminals and then clean one by one.

    This could be dangerous. No warning is given in the video. It is suprising it is from eHow. or I could be wrong.

    this is 12v battery.. no harm can be done…
    water resistance is high…current will flow, but very little…
    BTW: when flowing current through water, one terminal will have Heliume and the other terminal will have Oxigen 🙂 you will see bubbles….

    You should always remove the battery from the vehicle, it is much safer and you also get to clean the whole thing as well as the casing. Also, you should use a wire brush on the terminals and the poles as well. Dry with a clean rag before reinstalling and put a bit of Vaseline on the terminals to prevent corrosion.

    Yeah your battery is clean but what is up with the rest of the engine bay? Looks like it has never been cleaned EVER lol.

  14. leafedaduffa says:

    You always remove the negitive terminal never remove the positive unless you have already removed the negitive.

    Actually plain water is not a very good conductor of electricity. And the impurities in tap water increase it’s resistance. So the baking powder will be fine.
    But I agree with disconnecting before cleaning anyway. 😉

    Salt water, on the other hand, would definitely be dangerous! It conducts very nicely!

    and kind of soda will work like sprite,coke…

  18. jimhack3 says:

    After cleaning terminals, It’s good to spray a treminal protectant on them to minimize future corrosion, or you can spread some petroleum jelly on them which will do the same thing.

    OldHowlingHound below notes the most important safety item of eye protection, which should be mentioned explicitly, but the glasses the man is wearing work okay. Another good note would be to wear old clothes and especially gloves since bits of the solution can still be acidic. Really good video though. Thank you.

    dish soap works, water works, anything if you have a brush!

    @BigJohnIsOn he should also have said to cover up the distributor lol.

  24. Hitez04 says:

    Remove neg (-) terminal first. Then Pos (+) follow these same steps to clean, and you can clean the connecting terminals easier with them disconnected. ALWAYS USE PROTECTIVE EYE WEAR, the scrubbing can splash acid to any part of your clothes and skin/body, so be careful!! cover terminals with petroleum jelly, reconnect pos(+) first then neg(-)

    @strikeagle1 electrolysis of water = H2O = Hydorgen-2 parts, Oxygen-1 part
