Battery corrosion can be cleaned in two methods. One method uses water and baking soda and scrubbing. The other uses a can of cola to dissolve the corrosion. Both of these methods are inexpensive and can be performed in under 10 minutes.
Car battery corrosion is easy to spot and important to take care of. If corrosion is left untreated it can damage not only your battery but also your A/C and air intake systems. Corrosion is normally a white powdery substance that builds up on the terminals of your battery. It sometimes has a blue or green tint to it as well.
Battery corrosion can be cleaned using commercial cleaners, but some people swear by the cheaper at-home methods. Both of these methods use a chemical reaction to eat away at the bonds in the corrosion. One methods uses baking soda and water to make the corrosion easier to scrub off. The cola method is used mostly in emergency situations.
Anytime you're cleaning your battery you need a few common objects and tools. You need a 3/8 inch wrench if your terminals on top, or a 5/16 inch wrench if the terminals are on the side.
In the end this method shouldn't cost more than $5. The only cost should be getting some baking soda. This method only takes around 10 minutes.
Cleaning with cola should only be done in an emergency. You'll be using the same wrench size as in the previous method.
The cola method is cheap, all you need is a can of soda. It takes only 5 minutes and is great in a pinch.
If your battery can't hold a charge or can't be jumped, it's time for a new battery. To avoid getting to this point, it can help to know what causes these problems. Overloading a battery or improper use can cause these issues on top of other things.
Batteries can range in cost based on their life expectancy and reserve capacity. Brand name batteries are going to cost more, like Interstate or Optima. Another option is a rebuilt battery. This replaces the battery acid with a magnesium sulfate solution.
Sometimes an issue may seem like a battery issue, but it's an issue with another part of your car. The most common culprits are your alternator, a blown fuse, or a short in the electrical wiring. Differentiating these from a battery issue is important to save you time and money.
When it comes to car insurance, there are several factors to consider beyond monthly cost. A policy that covers you when you need it, has a low deductible, and offers several discounts can be hard to find - which is why we've done the work for you.
