Uneven shower spray? Check mineral buildup on the nozzles
Use the showerhead maker's instructions for gently removing mineral deposits from the spray nozzles.
Minerals in water may collect around showerhead nozzles. Delta recommends rubbing deposits from its Touch-Clean nozzles, while certain non-Touch-Clean models may be cleaned with a diluted vinegar solution. This does not make vinegar safe for every finish, so check the specific model first.
