The flexible silicone nozzles are designed to eliminate mineral build-up but are also easy to maintain should lime clog them. Should a water stream from a nozzle become uneven, get skewed, or clogged, rub the nozzle with your finger or use a soft toothbrush. Wash your hands first to keep grease off the nozzles or do it while in the shower and gently rub the nozzle. Do this easy maintenance as soon as possible and you’ll prevent bigger problems in the long run.Refer to this article for more info on shower care, maintenance and tips.
