Using the Brizo Kintsu Widespread Pull - Down Faucet Knob Handle Kit is easy. For normal water flow, just turn the knob. To use the pull - down sprayer, simply pull it out and aim it where you need. When you're done, return it to its original position. Here are some things to keep in mind. Don't use abrasive cleaners on the faucet as they can scratch the finish. Avoid hitting the faucet with hard objects to prevent damage. For maintenance, wipe the faucet regularly with a soft cloth to keep it clean. If there's any mineral buildup, soak a cloth in vinegar and gently rub the affected areas. This will help keep your faucet looking great and working well for a long time.
