What should I do if the stainless steel basin rusts?

Can use toothpaste or talcum powder, scrub with a soft cloth; 304 stainless steel basin doesn't mean it doesn't rust. Maintenance guide: 1. Don't leave water droplets on the surface. Water with high iron content may lead to the formation of brownish-red coloring marks on the surface (especially urban water quality); Suggestion: For young people who cook less, stainless steel cookers and basins should be wiped with dry rags. 2. Don't put mild steel or cast iron cookware in the sink for a long time. 3. Don't leave rubber dishwashing tablets, wet dishwashing sponges or other cleaning pads in the sink. 4. Household items, bleach or chlorine-containing food will all hurt the sink. 5. Don't put pickles, mayonnaise, mustard or other foods rich in salt in the sink for a long time. 6. Do not use scouring pad, abrasive sheet or abrasive material to clean the sink.
