You wouldn’t have thought it would take me so long to try this…

Given how many batteries I’ve had to deal with over the years, and how much I’ve bitched about contact corrosion, I never did a little study and let chemistry work for me. No, I was always the guy disconnecting cables and using abrasives. Which, in fairness to younger me, is how we did it in the auto shops.


Ian’s batteries have never given me a lot of problem but the main positive connection, which is the one on the upper right in the photo, has in the past few months positively bloomed with corrosion. Figures, since it was the hardest to get to in the box.

So this afternoon I suited and gloved up, grabbed an old toothbrush, mixed a bowl of baking soda and water, and went to war. I should have taken a ‘before’ picture: It was a short war. That method works great.

Which is good, because there’s about 20 connections on Landlady’s 24 smaller batteries that are turning green again and will shortly get the same treatment.

    Lots of spray coatings you can use to prevent that corrosion.

    Fairly cheap too.

    If the batteries are corroding at the terminals, you need to take the terminals off the batteries and clean the points of contact before coating them.

    If you can’t find some locally or via Amazon, email me and I can find some for you.

    I have a new anticorrosion coating that has worked well on my own batteries – I’ve now applied it to that contact on Ian’s and I’ll be using it on Landlady’s as soon as I get them cleaned.

    I used to use anti-corrosion pads back in the day when I owned beater cars. Easy to find on amazon.

    Dang! You just reminded me that a while back I purchased some terminal anti corrosion gel in a tube. Forgot to send it to you. Let me find where that thing ended up.

    Figure that once you do the cleaning, you dry the terminals and put a fine coat of this on them before re-assembly. Maybe you can do half with and half without, that way Anthony Faucci will be pleased with the results and the CDC will approve the method. (never mind me, lamestream fake news overloaded at the moment).

    Back in the day the clean, dry assembled terminals were coated with vaseline. If it wore off you just gobbed on a bit more. It would be funny if that plus a few other things were what is in the tube of anti corrosion gel.

  6. Mark Matis says:

    If you were to dump that bowl of “baking soda and water” into the batteries, the corrosion would stop…

  7. Matt says:

    If you have baking soda you probably have Coke, but in case you don’t, that works great too.

To the stake with the heretic!
