The answer to 'how to unclog faucet' is to first try removing the aerator (the small screen at the end of the faucet) and cleaning it. If that doesn't work, you can try using a plunger or a wire coat hanger to dislodge the clog. If the clog is deeper in the pipes, you may need to disassemble the faucet or call a professional plumber.
Before attempting to unclog the faucet, make sure to shut off the water supply to that faucet. This will prevent water from spraying everywhere while you work. Wear rubber gloves and safety goggles to protect yourself. If the clog is stubborn and you're not comfortable tackling it, it's best to call a professional plumber to avoid further damage to the faucet or pipes.
