Black composite sinks are among the most hard-wearing and luxurious sinks on the market today.

These handy nonporous kitchen fittings are manufactured from durable materials like quartz and composite granite that are almost resistant to scratch.

Nowadays, retailers explain that granite composite sinks are stain-resistant, fade-resistant, and heat resistant. Nonetheless, this is not the case altogether for black composite sinks.

Black composite sinks can accidentally scratch if proper care and maintenance are not done correctly.

Deep cleaning a black composite sink occasionally helps to eliminate odor, kill bacteria from the drain flange, and protect the black composite sink from minor scratches. Though always ensure no sharp object is in the sink before deep cleaning a black composite sink.

Luckily, this article addresses all the effective steps to remove scratches from black composite sink.

But before we proceed further, let us answer one question most homeowners ask.

Do composite sinks scratch?

This is a question kitchen users normally ask.

Remember that quality composite sinks are manufactured from durable quartz, high-quality granite resin, and plastic dust. Quality composite sinks rarely scratch as opposed to other composite sinks that are vulnerable to scratch.

When forged under high pressure and heat, a composite sink becomes non-porous, heat resistant, and scratch-resistant. However, a composite sink is not impervious to scratches.

Here are the two major causes of scratch on a black composite sink.

  1.       Placing sharp kitchenware (like knives, kitchen shears, grater, and other cutlery) in the sink
  2.       Using abrasive cleaners to scrub the surface of the sink

Therefore, you should always be cautious when placing and cleaning utensils in the sink. Also, use a washing-up bowl to avoid cleaning sharp utensils on the composite sink.

So, in short, the answer is yes. Composite sinks scratch if proper care and maintenance are not done.

Gently work your way through the entire surface of the sink for improved finish.

Leave the oil to sit for about 20 minutes then wipe the excess oil with a dry paper towel.

Repeat the above processes if the sink does not appear well-polished.

Clean the sink and get rid of any debris, then tape the sides of the sink before you begin using the sealant.

All sealants work effectively on clean dry surfaces.
