[ARC5] batteries message Glacial acetic acid eye protection. warning

[Richard Knoppow]

    Pure acetic acid, often called glacial acetic acid because it 
freezes at a fairly high temperature, is corrosive and should be 
kept of the skin and out of your eyes. It is a weaker acid than 
sulfuric or nitric acid. In photography it is usually diluted to 
28% as a stock solution and then diluted further for use. Most 
stop baths are about 2%. White vinegar is about 5% acetic.
    Vinegar is useful as a cleaner and neutralizer for alkaline 
materials. It can itself be neutralized by a solution of baking 
soda (sodium bicarbonate).
    A paste of sodium bicarbonate is useful for cleaning and 
neutralizing acidic materials such as spills from auto batteries. 
It should then be rinsed off with water.
