Mixture of epsom salt and distilled water. Mix 8 ounces of epsom salt in one quart of 150 degree distilled water. Drain fluid from battery and replace with saltwater mixture. Charge battery on the slowest charge setting you can with the vent caps removed.
No, it is battery acid corrosion caused by leaking fumes. Clean it off with water and baking soda which will neutralize the acid.
Baking soda and water. It will neutralize the acid. After removing the acid clean the post with a battery cleaning tool you can buy at any auto parts store.
Sulfuric acid fumes escaping from the battery.
Corrosion from the sulfuric acid. The electrolyte (water) inside the battery is a mixture of sulfuric acid and water. Those blue crystals is just corrosion. You need to clean it off. Remove the negative black (-) cable first and then the positive red (+) cable. With a mixture of 25% baking soda and water, clean all this corrosion off the battery and the cables. You can also use vinegar. Dry everything off and then clean the connections with a battery post wire brush you can buy at any parts store. Reconnect the battery cable positive first then negative.
it's not acid... it is corrosion and oxidizers
Sulfuric acid fumes escaping from the battery causes this corrosion.
My husband said it is caused by the vapor from the battery acid. It is the vapor of the battery acid leaking out of the battery, so the above answer is correct.
A solution of baking soda and water will clean battery acid, as will Coca Cola.
They absorb the sulfuric acid fumes which causes corrosion.
YES!!! Replace the car battery. The white corrosion seen on one of the battery terminals, is also inside the battery. The internals of a car battery contains lead plates , copper platres and sulphuric acid. During the (dis)charging process the sulphuric acid combines with the lead to form lead sulphate (The white corrosion). When sufficient of the white corrosion builds up inside the battery on the lead plate , it will eventually touch to copper plate. Whereupon the battery discharges and will not re-charge. The battery is //??@@#@!!! XX . So replace the battery. Sometimes, during the sulphuric acid /lead reaction hydrogen gas is liberated, if an electric spark occurs in the gas , there will be an explosion. So definitely change the battery!!!!!
Rinse with a mild acid such as vinegar.
Mix baking soda and water pour a bit on to neutralize the acid, use an old tooth brush to scrub it away. Be careful around active battery terminals. Also you may need a new battery if acid corrosion continues to form.
