What Causes Hard Water Spots on Stainless Steel?

Hard water contains dissolved minerals, primarily calcium and magnesium. When water dries on a surface, these minerals are left behind as a film or spots. On stainless steel, they can appear as white or cloudy marks that are especially noticeable on dark or polished finishes.

If left untreated, these spots can become more stubborn and may even lead to pitting or corrosion over time. That's why it's best to address them as soon as you notice them.

What You'll Need

• White vinegar (distilled white vinegar works best)
• Baking soda
• Soft microfiber cloths (avoid abrasive scrubbers)
• Spray bottle (optional)
• Dish soap (mild, like Dawn)
• Olive oil or mineral oil (for polishing, optional)
