This is a large can that should last a non mechanic years on personal vehicles.Simply spray on battery & terminals to remove corrosion and acid, let set a minute, then rinse with water.The issue is the terrible spray nozzle. It leaks out the bottom and makes a mess on the can and your hand. But, you can simply replace nozzle with a good one with a built in flange off another spray can laying around.

Works good my old truck was having issues connecting to the negative terminal but a cleaning with this fixed the issue.

I highly recommend to all. Instant results of exactly where the acid is present and at the same time neutralizes it. You will see yellow and a reddish/pink type color appear. Follow instructions, as you should with all products and rinse off. Done. Made the job a breeze.

Nissan Rogue battery terminals were caked in corrosion. I did a few easy applications with this product and it completely eliminated every drop. Use rubber gloves though and paper towel. I would definitely buy this again. Great price too!
Alex Baker –
Remarkably useful and instantly effective every time at cleaning corrosion. Just buy this and never worry about battery acid again!

I was surprised at how easy it was to clean the top of the battery and the terminals. It even cleaned the corrosion off bare wires so I could wrap them. The only bad side is you can’t control the spray nozzle. It sprays a wide path and gets on other things.

I also use this to clean up battery holders and corroded contacts from small devices that use cell batteries (AA, AAA, C, D, etc.). I just put a bit on Q-Tips and just carefully clean things up.
