For stubborn stains on your Quartz sink, use the eraser pad in Elkay’s cleaning kit or a Mr. Clean® Magic Eraser® with water. Towel dry with a cotton cloth.
For major stains or grime on your Quartz sink, a 50/50 white vinegar and water solution will help. Use the Mr. Clean® Magic Eraser®or dip a cloth into the solution and rub away the grime or stain. The solution should then be rinsed off and dried to prevent damage to your sink’s finish.
Another solution for major grime or stains, is a small amount of baking soda and water on a toothbrush. This should remove any nasty stains. Again the solution should then be rinsed off and dried to prevent damage to the finish of your sink.
DO NOT allow any part of your Elkay sink to soak in either of the above mixtures. It is also recommended to test the above mixtures on an unseen part of your sink to see what affect it has to the finish of your sink.
To prevent staining of your Quartz sink, do not leave standing water in your sink, especially if the water contains anything that could stain the sink (i.e. coffee or tea). Rinse anything that could stain the sink down the drain with running water and any splashes off.
