A car’s battery terminals, sometimes dirty or sulfated, make it difficult and even prevent the car from starting or starting. It is normal for them to get dirty over time and fail to make contact to send the required energy to the car.This happens because the metal of the clamps is sulfated. Sulphation occurs when the metal turns blue or greenish.
The first thing you should do is turn off the car and check the battery terminals to make sure they are sulfated or dirty. Then, using a screwdriver or wrench, loosen the screws and nuts holding the battery cables, starting with the negative cable located on the left, doing the same procedure with the right clamp, moving the cables away from the metal and preventing that both cables come into contact.
Remove the dirt or sulfate crust from the car battery by mixing a few tablespoons of baking soda in a bowl of water. Another trick is using a cola. Pour a stream of any of the products we specified on the car’s battery and let it act for a few seconds. Then run a cloth or dry cloth over the battery terminals.
Polish the car battery terminals by brushing or Rub the clamps with a metal bristle brush and the clamps that grip or screw the clamps into place. With this, the dirt remains well scraped off, and with a sandpaper from those with which they remove the imperfections of the wall, pass it through with a rag or a damp cloth, remove the remaining dirt and replace the cables. First, apply a thin layer of petroleum jelly or grease to the connectors to prevent them from sulfating again.
