How to Care for Your Kitchen Sink to Keep It Beautiful All Year Round
Expert tips from S-FLO specialists to clean and maintain stainless steel and granite kitchen sinks — easy to follow and helps extend the lifespan and beauty of your sink.

The kitchen sink is one of the hardest-working spots in the kitchen — exposed to water, grease, food scraps, and sharp objects every day. Proper care not only keeps your sink looking beautiful but also extends its lifespan by years. This article collects expert tips for maintaining both stainless steel and granite sinks, with easy-to-follow steps you can do at home.
Caring for Stainless Steel 304 Sinks
- Clean daily with a soft sponge and regular dish soap. Avoid steel wool or wire brushes that cause scratches to accumulate
- Dry after every use, especially around the rim and tap area, to prevent water spots caused by mineral deposits
- For rust stains from iron cookware left too long, use baking soda mixed with water and scrub gently along the grain of the stainless steel. Avoid circular motions as they create visible cross-scratches
- Every 1-2 weeks, use a dedicated stainless steel polish to maintain shine and help prevent water marks
- Avoid leaving bleach or highly chlorinated cleaners in the sink for long periods, as they can corrode the surface over time — even on durable grade 304 stainless steel
Caring for Granite and Special Material Sinks
- Granite sinks like the S-FLO Granite are more scratch-resistant than standard stainless steel, but avoid placing hot pans or pots straight from the stove directly on the surface, as sudden high heat can degrade the finish
- Clean with warm water mixed with mild dish soap and a soft sponge. Avoid harsh corrosive chemicals like concentrated bathroom cleaners
- For stubborn stains, apply baking soda mixed with a little water, leave for 10-15 minutes, then rinse. This removes stains without damaging the surface
- Dry after use to prevent limescale buildup in the microscopic pores of the surface
General Tips for All Sink Types
- Don't let food scraps or grease sit overnight — wash immediately after each use
- Check the strainer and drain regularly to prevent clogging and unpleasant odours
- If your sink has a built-in drainer, avoid placing very heavy items or applying strong impacts, as this can damage the welded joints over time
- Clean the tap and surrounding accessories at the same time for overall cleanliness of the washing area
