How to Remove Hard Water Spots from a Stainless Steel Sink

Hard water spots on a stainless steel sink can make it look dull and crusty. Here's a practical, surface-safe guide to remove them without damaging the finish.

Part 2: Step-by-step method

If the spots are still visible after this, you can repeat the process. For very stubborn spots, you can increase the vinegar soak time to 15 minutes, but always test on a small, inconspicuous area first.

What Not to Do

Stainless steel is durable, but it can be damaged by harsh chemicals and abrasive tools. Avoid the following:

  • Do not use bleach or chlorine-based cleaners. These can cause pitting and discoloration.
  • Do not use steel wool or metal scrubbers. They will scratch the surface and make it more prone to future spots.
  • Do not let vinegar sit for too long. Prolonged exposure to acid can dull the finish.
  • Do not use abrasive powders or scouring creams. They can leave fine scratches that trap dirt and minerals.

Fresh vs. Dried Spots

The method above works for both fresh and dried spots, but the approach differs slightly:

  • Fresh spots: These are usually light and may come off with just a damp cloth and a little dish soap. If they persist, use the vinegar and baking soda method.
  • Dried spots: These are more stubborn and may require a longer vinegar soak. You can also make a stronger paste by using less water in the baking soda mixture.
