I remember learning about this back in high school mechanics, but its been a while. I was just wondering what causes that powdery stuff you see around the battery terminals/connectors sometimes? and what can you do to prevent it from happening?

 

I know they sell a preventative spray, not sure if it's at crappy tire or not. They also have a cleaner. I think what usually starts the corrosion someone correct me if I'm wrong, is moisture.

 

Yup Cj is right, I'd also like to add that you can use a metal bristal brush to clean it up, they also have a spray.

 

Now the questions is, how did that moisture get there? hmm. but its a bit cold, i will look in2 using the metal brush to clean it up soon. Thanks Cj and Mr.T for the info

 

wd40 works great cuz it repeals water...

 

you can use vasoline or silicon lube on the terminals
