How to Clean and Maintain Your Stainless Steel Undermount Sink

Stainless steel undermount sinks are a popular choice for their durability and sleek, timeless aesthetic. However, to keep them sparkling and prevent the common issues of water spots and light rust, you need a specific, non-abrasive maintenance routine.

The Daily Clean: Mild Soap is Best

For daily maintenance, use a simple combination of warm water and a small amount of mild dish soap. Use a soft cloth or sponge and always wipe in the direction of the grain (the faint lines visible in the steel). Wiping with the grain helps hide minor scratches and ensures a streak-free finish. The most crucial step is drying. After cleaning, wipe the sink completely dry with a clean microfiber cloth to prevent minerals in the water from leaving spots.

The Deep Clean: Vinegar and Baking Soda

For a deeper clean that removes minor stains and water spots, you can use two kitchen staples:

1. Baking Soda Paste: Sprinkle baking soda over the sink basin and scrub gently with a damp cloth, still following the grain. Baking soda acts as a mild abrasive that is strong enough to remove stuck-on grime but gentle enough not to scratch the steel. Rinse thoroughly.
2. Vinegar Rinse: To tackle stubborn water spots, spray the sink with a solution of half white vinegar and half water. Let it sit for a few minutes to dissolve mineral deposits, then rinse well and, again, dry completely.

The Finishing Touch: Polishing and Protection

To give your stainless steel a truly brilliant shine and provide a layer of protection against future spots, apply a few drops of mineral oil or a dedicated stainless steel polish to a clean cloth. Rub the oil into the sink, following the grain. This protects the finish and causes water to bead up, making the next cleaning much easier.

What to Avoid

Never use steel wool, abrasive scrubbing pads, or chlorine bleach. Steel wool can scratch the surface and leave behind tiny iron particles that lead to "flash rust." Chlorine bleach is highly corrosive and can damage the protective layer of the stainless steel, leading to permanent pitting.
