Cure For Battery Terminal Corrosion
My daughter drives her 2012 Camry ~40k miles a year and has unbelievably bad battery terminal corrosion. My wife drives her 05 Camry ~12k miles a year and has pretty bad BTC.
I drive my 09 Yaris Hatch 5k miles a year and have almost none. You can PREVENT BTC by coating the terminals with a thick layer of wheel bearing grease. My daughters car had corrosion all over the battery, all over a nearby computer, and all over the nearby fusebox. The terminals had to be replaced as did the hold downs by the delaer (shes rich! ) Now a year later her terminals are good and clean of corrosion with a good coating to wheel bearing grease on them!

I think it depends a lot on the weather and the region you live in. Driving the Yaris for five years now and battery corrosion never occurred.
I think you may need to use battery corrosion protection spray regularly. |

Battery corrosion is only caused by the battery leaking acid. Splurge and and install an AGM battery and never worry about it again.

Interesting I didn't know that. But wheel bearing grease is free and prevents the corrosion whereas an AGM battery is $$$. My observation is the more you drive the more corrosion. Which might now be wrong! Theres no grease on the terminals of my Yaris battery (5k mile/year) and no corrosion after 6 years...

Tried that and it helped a little. But it still came back. One good application of WBG and it never comes back...

Yeah it caused by the car's charging system overcharging the battery constantly and causes the battery to vent excess hydrogen buildup. This also caries acid with evaporating water.
Best thing is to just hose it off once a month if she drives that much. |

If it's rather minor, and only on the terminals, I just scrub it down with baking soda and water, let it dry, and then give it a nice coating of wheel bearing grease. Usually does the trick. However, if it is all over the place, or the above procedure doesn't stop it, you should replace the battery. My wife's Suzuki SX4 had a real problem with this. So bad that it ate through the positive lead that connected to the post connector and left her stranded. Because of the rubber cap over the lead, I hadn't noticed the corrosion. I replaced the connector and it was fine for a while, but started to build up again. Everything I tried failed until I replaced the battery. After that, I cleaned the terminals, and haven't had the issue since. So, I would replace the battery.
I drive my Yaris far more than she does (230,000 miles on it) and have never had an issue with corrosion.

A Google suggestion is petroleum jelly, for its hydrophobic and electrical (insulating) properties. Slimy stuff, though.
I put it on the wife's car, which had the white corrosion caked on the positive terminal. Wire brush, reconnected, wiped on a smooth layer. 6 months later, not a trace of corrosion. |

Würth #0890104 It's what the professionals use. Petroleum-based lubricants, like Vaseline and heavy-duty bearing grease, may have a tendency to:
Vaseline releases flammable vapours. I would not advise it. |

There won't be any damage done. Vaseline has been used for years by cheap-asses without trouble, although yes, I suppose there could be a small chance of danger (to you, not your battery).

Well, the battery itself releases flammable vapours when charging so where do you draw the line?

Well then, now that I've established myself as a paranoid cheapass, I should just shut my trap and clean off this greasy mess.
