Yesterday, I posted about an intermittent electrical issue with my Odyssey. A few of you suggested cleaning the battery terminals. I'd say this one needs some cleaning. Any suggestions on the best way to clean this up?

Wire brush.

A wire brush, a can of Coca-Cola and a some water to rinse it off when you are done. And go/

1. Wire brush and a bottle of coke

2. Go the autoparts store and get some of the chemically-treated felt washers and dielectric grease

3. Don't overtighten the terminals when you put them back on

I know just who to call.

Wirebrush on disassembly, having first placed a paper towel/rag to catch bits that are knocked loose. While most of what's there is copper sulfate and the like (just salts), there will be some sulfuric acid dissolved in it, so it's not good to let that roam free. There are even specialty battery terminal cleaner wire brushes for this, if you feel so inclined. The big thing, though, is neutralizing acid in the area - you can get from auto parts stores a spray to do that (basically aerosolized frothy baking soda with a colorant) and a spray to apply to the connections after you're done.

What Loblaw said. These are the felt washers.

Dr Pepper and a wire brush?

Is that an alkali leak?

They make a tool for that. A battery terminal brush.

The bottom is a brush-lined hole that fits over the battery post, and cleans it when you twist.

The cap covers a spiral brush, shown, that can clean the wire terminal ring also.

Then install fiber washers treated with chemical to inhibit further corrosion, before re-installing the wire terminals.

Then finally, spray on a bit of battery terminal protector and sealer over the the ring terminal and post when attached.

final step: reset radio presets, clock, etc... from having the battery disconnected. Done and done.

Windex also works very well

nope. It isn't an alkaline battery. Just run of the mill car battery.

That looks like... a fleshlight for batteries. Can't unsee it.

That says more about your frame of mind than anything else.

*That wasn't a critic BTW, just kidding :p

Throw some Baking Soda into a container, add water, then get an old toothbrush (you know you need to change yours, probably, right?) Dip brush into water/paste and brush away until it's all gone. Fizz city. Hose down. Then do the wire brush/clean thing, then the washers to help with the future.

Thanks, but I already took care of it .
