How To Get Corrosion Off Car Battery. Corrosion on a car battery is dangerous to the lifespan and efficacy of your battery to your clothes if you try to clean it and can cause skin irritation if proper protective equipment is not used. Remove the battery terminals and use your brush to remove some of the corrosion.
The process is very simple. I have one in my toolbox at all times. Do not put a lot of pressure on the clamps to avoid damage.
An inexpensive way to keep corrosion from building up on your cars battery terminals is to apply a tablespoon of petroleum jelly to both the positive and negative posts.
Use a toothbrush to agitate and remove the corrosion entirely from the terminal. Youll be surprised how times an old toothbrush can come in handy not just to clean car battery corrosion. Reconnect the battery connecting the positive terminal first then the negative one. Place a drop of vinegar or lemon.
