Another abrasive you can try is very fine grain sandpaper (e.g.. 1,000 or 1,200 grit) – used wet – to gently rub away the stain. This is used very effectively on burn stains on marble so should also work well for sinks made of similar natural stone or their composites.
Sprinkle baking soda over the burn mark. Dampen a cloth or a soft-bristled toothbrush with white distilled vinegar. Scrub the stained area gently in a circular motion to remove the stain. Rinse the area with cold water to remove any baking soda and vinegar residue.
The key is not to use straight vinegar on the sink, but to make a mixture that is 50% water and 50% vinegar. Apply the mixture to the limescale stains, and scrub with a nylon brush until clean. Rinse with clean water.
For surface marks, first use a soft cloth and soap to clean the surface, and then apply a thin layer of baking soda or toothpaste to the mark. Let it sit there for a few minutes. Then use a toothbrush or soft bristle brush to scrub the burnt surface. Clean again. Repeat as necessary until the mark is gone.
Cleaning granite composite sink with baking soda, white vinegar and sunflower oil, first clean well with baking soda and vinegar, then rinse and dry, then add sunflower oil and wipe it clean with tissue. The more you do it the better will become, better than any other chemicals cleaners that are toxic and never as good.
Regardless of the color, avoid using harsh chemicals on your composite sink. They can damage the surface and dull the finish. Instead, opt for natural cleaning solutions, such as a paste made from baking soda and water.

Spray cleaners (irrespective of the label claims). Photographic developing solutions. Bleach - diluted or neat, especially do not soak items in the bowl for any period.
If the burn stains are stubborn, add vinegar to the mixture. To clean the burners, you need to mix 50/50 water and vinegar in a spray bottle and apply the mixture. Leave it to stay for 15-20 minutes. Use a non-abrasive pad or toothbrush to remove any food residue.
Sometimes a light scorch or cigarette burn can be removed by rubbing the browned area with superfine (#0000) steel wool. If any brown stain remains, apply a chlorine laundry bleach to a cotton swab and place on stain, allowing time for bleaching to occur. When all stain is removed, sponge with clear water.
Pour citric acid around sink drain stain. Let it sit for 10 to 15 minutes. Brush ring and rinse.
Stubborn stains can be removed with a diluted mixture of water and bleach, or denatured alcohol, on a cotton cloth. Once you've completed cleaning, rinse with water and wipe dry. Please note that it is important to avoid strong acidic products, such as toilet or oven cleaners, as these may damage your countertop.
This type of sink is easy to clean
Keeping it clean is also important. You can use a magic eraser sponge to remove stains and a 50/50 water-bleach solution for cleaning.
Baking soda is your go-to for cleaning a burnt pot or pan because it has mild abrasive properties and its alkaline pH can help neutralize acidic burnt foods.
Avoid substances like bleach and harsh chemical cleaners as this could damage the surface of your sink and cause staining. Chemicals to avoid include ammonia, sodium hydroxide, hydrochloride and sulphuric acid.
White vinegar is another helpful pre-treatment that works well to soften burn marks on textiles. Vinegar can dissolve the burn mark and facilitate its removal as a natural acid.
Burn marks may not go away completely, but they will fade over time. Treatments like topical creams and laser therapy can also help reduce the appearance of a burn scar. The severity of scarring and how much its appearance can be reduced depends on the depth of the burn and how it was initially treated and managed.
4: Toothpaste
Another misconception about burn treatment is that you should put toothpaste on it — but again, this can make it worse. Toothpaste can intensify the pain from the burn and increase the risk of infection and scarring. The ingredients in toothpaste do not have the healing properties to treat a burn.
Mixing vinegar and baking soda causes an immediate chemical reaction. This reaction forms water, sodium acetate (a salt) and carbon dioxide – the fizzy part. The amount of carbon dioxide gas that is produced from baking soda is remarkable – one tablespoon (around 18 grams) can release over five litres of gas!
Weight: Composite sinks are typically heavier than stainless steel sinks, which can make installation a bit more challenging. Ensure your benchtop can support the weight and consider consulting a professional installer if needed.
Hard water and minerals in the water can leave white stains on your sink.
Since the material is not entirely heat proof, you'll want to avoid pouring boiling water in a granite composite sink.
