Battery acid can be cleaned up with baking soda, soda ash or a specialized cleaning substance, such as North American Bioindustries Battery Acid Cleaner and Neutralizer. These materials neutralize the dangerous aspects of the acid so it can be cleaned up.
These materials result in fizzing when introduced to acid, and when the fizzing stops it is safe to absorb the leftover liquid with a material, such as kitty litter or clay, that quickly absorbs liquid. This can then be disposed of according to the local hazardous material disposal guidelines. Throughout the process, wear protective gear, such as gloves, to prevent damage to skin and clothes from the corrosive acid.
When acid leaks inside of a compartment, including car battery bays and electronic devices, the exterior of the battery will corrode. With this, the battery cannot properly provide power, so the device is unable to work as well. Corrosion can also result in more acid leaking out, causing further damage.
To clean corrosion, use baking soda, water, vinegar and cotton balls or soft cloths. After the dry material has been brushed away, add vinegar or a mixture of water and baking soda to the corrosion. Like liquid spills, this causes fizzing, and once the fizzing has finished the area can be cleaned and the acid covered materials disposed of. After the area has been rinsed with water and dried, it is safe to use again.
