Do I need a monkey wrench to remove faucet aerators? Do I need a monkey wrench to remove faucet aerators?
Faucet aerators are exposed to constant water, the chemicals it contains and, in some areas, hard water deposits. These deposits can bond the threading of the screw-in aerator to the faucet, which can make it very difficult to remove. If the faucet aerator is stuck badly, you can use a monkey wrench to loosen and remove it. Be careful to not scrape or scratch the chrome. You don't have to have a monkey wrench—a pair of pliers will also work. You can put tape around the chrome to avoid scratching it. WD-40 will also loosen a stuck faucet aerator.
