Stopping battery acid corrosion
#1
My wonderful ( Rolleyes ) stock ACDelco battery decided to start peeing down my engine bay. The battery has long been replaced, but the corrosion is still continuing. How can I neutralize it?

Baking soda and water mixture.

That's it? What kind of mixture? 50/50?

Actually use about 1/4 cup of baking soda...fill the rest of the medium sized bottle with water. Put it in a spray bottle and it will "eat" the corrosion on the body and around the posts (if any). You can also use Coke...works just as well but if you dont get it all it obviously becomes sticky. Rinse everything after your done with regular water but dont get it in the battery itself.

Yes, Something they tried to teach me in high school. There is acid and bases. Battery acid is well, a acid. Baking soda and water is a base. It neutralizes acid. Coke does not work nearly as well.

Coke is an acid, it will eat the corrosion off of the battery terminals to give you a clean connection.

Just when you thought you knew everything....

1. In many states the highway patrol carries two gallons of Coke in the trunk to remove blood from the highway after a car accident.

2. You can put a T-bone steak in a bowl of coke and it will be gone in two days.

3. To clean a toilet: Pour a can of Coca-Cola into the toilet bowl... Let the "real thing" sit for one hour, then flush clean.

4. The citric acid in Coke removes stains from vitreous china.

5. To remove rust spots from chrome car bumpers: Rub the bumper with a crumpled-up piece of Reynolds Wrap aluminum foil dipped in Coca-Cola.

6. To clean corrosion from car battery terminals: Pour a can of Coca-Cola over the terminals to bubble away corrosion.

7. To loosen a rusted bolt: Applying a cloth soaked in Coca-Cola to the rusted bolt for several minutes.

8. To remove grease from clothes: Empty a can of coke into a load of greasy clothes, add detergent, and run through a regular cycle. The Coca-Cola will help loosen grease stains. It will also clean road haze from your windshield.

9.The active ingredient in Coke is phosphoric acid. Its pH is 2.8. It will dissolve a nail in about 4 days.

10.To carry Coca Cola syrup (the concentrate) the commercial truck must use the Hazardous material place cards reserved for Highly Corrosive materials.

11.The distributors of coke have been using it to clean the engines of their trucks for about 20 years!



This is why I drink Pepsi. :yesyes:

Yeah, STRAIGHT phosphoric acid can dissolve a nail quickly (depending on many other factors), but the diluted phosphoric acid in Coke will not.

Ctiric acid is some pretty crazy shit too. We once had a 10 gallon container of hydrogen peroxide when I worked in the chem lab at Johnson & Johnson. It was a health hazard to anybody near it, it was so strong. The bottle you keep in your bathroom in your bathroom is almost pure water.

Damn, I miss that job.

Old timers like to use Coke as a radiator flush. It dissolves a lot of the crud. I would use it that way if the rad was out of the car, you could plug the inlet/outlets and leave it sit in there a few days, then flush it clean... but I'd prefer NOT to let it etch the head gaskets and such in an enclosed engine system, with the rad still hooked up to the block etc.
