1. Newly renovated users can apply a thin layer of oil to the sink surface to prevent rust from forming due to metal debris during the renovation process. Additionally, if the sink will not be used for an extended period, a coat of oil can also be applied to protect the sink.

2. Regularly clean the sink with a neutral cleaner, gently wipe it, then rinse thoroughly with clean water. Dry with a sponge or cloth, avoiding steel wool or rough brushes to prevent metal particles from adhering to the sink walls, which can lead to rust stains over time or scratch the surface. Do not leave water droplets on the sink surface, as high iron content water can cause brownish staining; if staining occurs, suggest using a dilute vinegar solution to remove the deposits, followed by a thorough rinse with clean water.

Do not leave lemons, sauces, pickles, mustard, or other salty or corrosive foods in the sink or on the countertop for extended periods, as this can erode the sink and leave difficult-to-clean stains on the surface.

4. Avoid prolonged contact between the sink and strong bleaching powder, household chemicals, and soap. If such contact occurs, Su General Manager advises the owners to rinse with water and immediately dry with a towel.

If there are floating rust or mildew spots on the sink, apply five-cleaning powder or toothpaste to the rust and spots, then wipe clean with a cloth. Remember not to use scouring pads, abrasive sheets, or abrasive materials to clean the sink.

Do not cut food or chop hard objects directly on the sink panel to avoid scratching the sink or causing deformation.

Please avoid using sharp or hard utensils such as forks and cookware to strike the sink, as this may scratch or dent the sink's surface.

Do not leave低碳钢 or cast iron cookware in the sink for extended periods, nor should rubber dish scrubbers, damp dish sponges, or other cleaning pads be left in the sink.
