1. CRC 7.50z Good Battery Terminal Cleaner Spary

CRC 7.50z is a very good battery terminal cleaner and Protector because its is made with high quality material like: Butoxyethanol, Sodium bicarbonate, Petroleum gases, liquefied, sweetened, Detergent/Inhibitor mixture.

One of the problems I face most of the time is corrosion on my car battery. We can do a few things to deal with the battery corrosion.

My favorite battery corrosion cleaner is CRC battery cleaner with acid indicator spray. I have used it on many cars to clean their batteries. It worked perfectly for me and surely will work for you as well.

The coolest part of this cleaner is that it changes its color. When you spray it over the corrosion, as soon as it comes in contact with the acid, it changes from yellow to pink. That means it neutralizes the acid.

This spray is easy to use. But always use protection when handling acid and corrosion. Before spraying, I clean the area using a wire brush if it is too corroded. After spraying, I allow it to sit there for a few minutes, depending on the corrosion intensity. After five minutes, I wipe it off with a scotch towel. It looks more battery terminal now than before.

It is not completely done yet. I could still see corrosion under the cable. So, I took off both terminals to remove the battery for more cleaning. You need to make sure that the terminals are not damaged by corrosion. Otherwise, you would need a new terminal set before removing the damaged one.

After removing the battery, I did some more cleaning using hot water spray and then wiped it off. You need to be extra careful that none of the liquid should mix with the battery acid.

I want to prevent this from happening in the future. So, before putting both terminals back on battery, I put special felt on the battery post. These felt have a solution on them that neutralizes the gas. The solution will absorb the gas instead of allowing it to react. That’s it.

CRC battery cleaner is helpful for maintaining the battery’s health. However, there are some pros and cons to this cleaner.

Pros:

Fast action

 Easy to use

 Multi-purpose

Cons:

Not suitable for all materials

 May cost you more depending on the size you buy

 Harmful if inhaled
