Faucet water spots? Wipe gently and dry the finish instead of scrubbing
Evaporating water can leave mineral marks on faucet finishes. Use a soft damp cloth and then buff dry; avoid abrasives and bleach-based cleaners.
Delta Faucet explains that water left to evaporate can deposit minerals and recommends a soft damp cloth followed by drying. Chemical compatibility varies by finish and manufacturer, so do not assume acids are safe on every tap.
