How to Clean a Kohler Black Sink

Put on rubber gloves. Spray the sink down with a non-abrasive bathroom cleaner if the sink is enameled cast iron. If the sink is vitreous china, you may a use cleaner containing soft abrasives, but avoid hard abrasives. If soap scum is present, use a bathroom cleaner specified for this use.

Wait for five minutes to allow the cleaner to dissolve soap scum or kill bacteria on the sink.

Wet a sponge under the faucet. Scrub the sink to loosen debris from the surface. Run the faucet again, rinsing out the sponge and rinsing off the sink.

Wipe the black sink with a towel to dry it.
