Burn marks on a stainless steel sink usually occur when hot cookware, heated utensils, or scorched food residues touch the surface. These marks may appear as dark spots, rainbow discoloration, or dull patches. Although stainless steel is heat-resistant, high temperatures can alter the metal’s surface finish. Fortunately, most burn marks can be removed safely with proper cleaning methods.
Rinse the sink with warm water to clear away debris, grease, or burned particles.
Wash the area with dish soap and a soft sponge to remove surface grime before deeper cleaning.
Sprinkle baking soda over the affected area.
Use a damp sponge or cloth to scrub gently in the direction of the stainless steel grain.
Baking soda helps lift light burn residue without scratching the surface.
Rinse with warm water to see if the mark has faded or if deeper cleaning is needed.
Spray white vinegar onto the burn mark.
Let it sit for 5–10 minutes.
Vinegar helps dissolve mineral and heat-based discolorations.
Scrub using a soft cloth following the grain, then rinse thoroughly.
Mix baking soda with a small amount of water to form a thick paste.
Spread it over the burn mark and let it rest for 15–20 minutes.
Scrub gently with a sponge or soft brush.
Persistent burns may require 2–3 rounds of paste and scrubbing.
Apply a stainless steel cleaner to a microfiber cloth.
Rub the cleaner in long strokes that follow the grain of the steel.
This helps eliminate discoloration and refine the surface.
For rainbow-like discoloration, scrub first with baking soda, then spray vinegar, allowing the fizzing reaction to break down the stain.
Wipe clean and buff dry to restore clarity.
Apply a small amount of mineral oil or stainless steel polish to a soft microfiber cloth.
Buff the treated area in the direction of the grain.
Polishing enhances shine and provides a temporary protective layer.
Do not use:
Steel wool
Abrasive pads
Harsh chemical cleaners
These can scratch the metal, worsen discoloration, or damage the protective chromium layer.
Allow pans to cool before resting them on the stainless steel.
A grid prevents direct contact between hot items and the sink surface.
Prompt cleaning prevents stains from hardening.
A polished sink is more resistant to heat marks and discoloration.
Burn marks on a stainless steel sink can be removed effectively using baking soda, vinegar, stainless steel cleaning products, and gentle polishing. By treating the stain progressively—from mild cleaning to deeper restoration—you can eliminate discoloration and restore the sink’s original shine. With proper care and prevention, the stainless steel surface will remain bright, smooth, and durable.
