There are many chemicals available on the market today that are suitable for use as neutralization chemicals. The most commonly used chemicals are discussed in an article available here, and are in use for good reason.

Sulfuric Acid H₂SO₄

Sulfuric Acid H₂SO₄: The most widely used and produced chemical in the world. Available in concentrations ranging from 0% to 98% sulfuric is also the least expensive acid to use. Sulfuric acid is used almost universally for neutralization reactions. It is easier and safer to use than HCl or HNO₃ and is more potent than all of the other acids except for phosphoric. Although adverse reactions are always a possibility, they are rare. If calcium is present then calcium sulfate (CaSO₄), also known as gypsum, will precipitate. Unless calcium is abundantly present this is not an issue. Sulfuric acid is typically used in concentrations ranging from 25% to 96%.

Generally this is a safe and inexpensive acid to use for the neutralization of alkaline materials.
