Warm Tips： Stainless steel is not completely rust-proof. In pure water environments, 304 stainless steel has relatively good corrosion resistance and is not prone to rust. However, if water contains oxygen, salt, or other corrosive substances, it may accelerate the corrosion process of stainless steel. In addition, water temperature and water quality also affect the corrosion resistance of the material.

If rust removal is needed, a special stainless steel cleaner can be used. Yellow spots and corrosion on stainless steel surfaces can be removed by soaking in white vinegar, wiping with baking soda paste, rubbing with lemon juice and salt, using a special metal cleaner, polishing with potato and dish soap, etc., depending on the severity and cause of the yellow spots.

Meanwhile, for the health of your pets, it is recommended to clean the inside of the water dispenser and replace the filter element in a timely manner (replace every 7–10 days, no longer than 14 days at most).
