Westheimer Plumbing & Hardware The best thing is to clean it out everyight after you are finished with dishes. You can use just regular soap and water and then dry it out. If it starts to get a calcium build up you can use Kaboom to clean it. You can also use vinegar. After you clean it whipe it dry and put some mineral oil on a rag and whipe it around. It will help the water bead off and not leave the spots.

Westheimer Plumbing & Hardware Yes it is scratch and stain resistant. We sell more of the black and brown sinks other any other color. One of our showroom managers has had hers for 9 years and it still looks brand new. Both my parents and in-laws have the black sink at their own houses and they are fabulous! Please let me know if you have any other questions. You can always email me at Carrieb@westheimerplumbing.com
Have a great weekend!
