CRC 05023 Technician Grade Battery Cleaner with Indicator - 11 Wt Oz.

Fantastic cleaner! Works quickly and the pink color is helpful to know you got all the corrosion off. I've already used it to fix my battery and my neighbors car battery connection. Be sure you follow directions, use it twice and dry thoroughly and you're connection will be like new. Recommend pairing with their insulation spray to prevent corrosion if you park outside.

Strong spray, used on a bobcat fuse lock, soaked and then cleaned with a bristle brush, for the prongs super clean, rinsed and then slacked with WD40, eyeballed it, treated with dielectric grease and wil hope to not see any maintenance for the future. I use this on many applications so make sure to read instructions for the application. The foaming action is superior!!! Make sure to buy a can for a friend!

Use gloves, not just for any acid you might get on your hands but this stuff stains skin, you can wash it off with some scrubbing. The whole top of my battery turned pink, followed the instructions and after the second treatment no more pink. Use plenty of water during rinsing just to make sure you get it all washed out. Doesn’t smell too bad, but there is an oder to it. Overall seems like good stuff. Will buy again.

This works good to help remove corrosion, but you still need a wire brush to get the connection really clean. Don’t rely on this product all by itself.

Works well. No complaints
