When it comes to the battery, simply replace the 4xAA alkaline batteries when the low - battery indicator lights up. Make sure to keep the sensors clean to ensure proper activation. To maintain the faucet's look, wipe it with a soft, dry cloth regularly. Avoid using abrasive cleaners as they may damage the Brushed Stainless PVD finish. This faucet complies with ADA guidelines, so it's suitable for all users. Also, remember that this is a non - returnable item.
