CLEANING YOUR SINK. Synthetic detergents used for dishwashing leave the sinks clean and free of incrustations of grease, so that they rarely need scouring. If you do need an abrasive, select the finest. Coarse scouring powders scratch the finish, making it harder and harder to keep clean. Always rinse away carefully any powders you use. Stains can be removed easily from a kitchen sink with household bleach. Just fill the sink with warm water, add a quarter of a cup of bleach, more or less, and let it remain until the stains are gone and the sink is uniformly white. Sponges and dish mops can be bleached at the same time. The removal of iron and copper rust stains from porcelain enamel are discussed in relation to bathrooms.

FLUSH THE DRAIN of you kitchen sink with plenty of hot water after using it. This cleans the drain and leaves the trap filled with fresh water.

To do this, close the drain opening and run two or three inches of cold water into the sink. Then, with cold water still running, turn the top of the unit to the "on" position and let the grinder run until the sink is empty. Do not use chemical drain openers if you have a garbage grinder. They are not needed and might be harmful.

If a bottle cap or other forbidden item accidentally gets into a garbage grinder, the gadget will protest by emitting strange noises. Turn the motor to "off," remove the top, and take out the obstruction. The motor cannot operate when the top is off.
