Show me your corroded battery terminals!

More of a PSA than anything, go clean them and snap a pic for posterity!

 

mine aren't.

first thing i do whenever i get a new-to-me vehicle is clean the terminals, apply dielectric grease, and use the foam donuts that i think are semi-useless.

hasn't failed me yet

 

I use CRC battery terminal protector spray, it eliminates the chance of corrosion. I've been using it for over 20 years on different vehicles and never once had any corrosion. A red dye is used to verify coverage.

 

Me too.
. 20+ years using CRC and never any corrosion.

 

Same experiences with the CRC here. Good stuff. However, I started using Fluid Film instead of the CRC product back in 2020…and have had zero issues, just like the CRC. Just food for thought.
