How to clean composite sinks

Updated February 21, 2017

Composite sinks are a blend of resin and natural stone, which combine to create a sturdy, durable sink surface. The composite retains its appearance for the most part, but as usual you need to clean the sink regularly to keep it looking its best. A mild cleaning solution combined with a slightly stronger stain removal routine will keep your composite sink looking clean and attractive.

Drizzle washing up liquid over a wet sponge, and scrub the composite sink, including drain and tap hardware. Flip the sponge over to the nylon scrubber side to remove sticky build-up.

Rinse out the sponge, and rinse your composite sink as well. Wipe the wet sponge over areas the sink tap will not reach.

Squeeze out the sponge, and drizzle one corner of the sponge with oxygen bleach. Rub this gently over any stains, repeating until all stain build-up is removed.

Rinse the sink when finished.


Do not use harsh chemicals, and do not pour nail polish remover, oven cleaner, paint thinner or any similar elements into the sink.
