As part of basic vehicle maintenance, which liquid is recommended for cleaning the battery terminals and metallic components if they are sulphated?

Question

DentroTest · Accepted Answer

The correct answer is distilled water. Battery terminals tend to sulphate over time, becoming covered in a whitish layer that hinders the flow of electric current. To clean them, mineral water should be avoided as it contains salts and minerals that conduct electricity and can accelerate corrosion or cause short circuits. Alcohol is highly flammable and dangerous near a battery, which can emit explosive gases and generate sparks. Therefore, distilled water (or hot water with baking soda in workshop practice) is the safe option for cleaning without leaving conductive residues. Once clean and dry, they should be protected with grease or petroleum jelly.
