Use professional cleaner: The commercially available stainless steel cleaner can effectively remove watermark spots, but the instructions for cleaning should be followed.

Precautionary measures: Minimize the time that water stays on the surface of stainless steel, dry the water drops on the surface or pour out excess water in time to prevent watermark spots.

Before trying the above methods, it is best to test in an inconspicuous place to ensure that the surface will not be damaged.

The method of cleaning the surface of stainless steel workpiece is slightly different from that of cleaning the flat surface of stainless steel. Here are some methods that may be useful:

Use professional stainless steel cleaner: There are many professional stainless steel cleaners to choose from in the market. You can choose the appropriate cleaner according to the stain degree and the area to be treated, and follow the instructions of the cleaner.

Hand grinding: The stubborn stains can be removed by hand grinding. Fine sandpaper can be used to gently polish the stained parts on the surface of the workpiece, and be careful not to excessively polish them.

Electrolytic polishing: If there are obvious stains or scratches on the surface of the workpiece, electrolytic polishing can be considered for repair. This method requires the use of special equipment and chemical solutions, and it is best to be operated by professionals.

Hydraulic cleaning: For workpieces with large surface or accumulated impurities on the surface, a high-pressure water gun can be used for cleaning. High-pressure water flow can quickly wash away most stains and impurities, but it is necessary to control the water pressure to avoid damage to the workpiece surface.

It should be noted that stainless steel workpieces need to be protected from scratches, collisions and other damages during cleaning. The cleaning of stainless steel workpiece surface should be selected and operated according to the specific situation to ensure the cleaning effect and safety.
