Your Countertops
The first step to preventing granite stains: Get your countertops sealed a few times as soon as it's installed, says kitchen designer Florence Perchuk. You'll know it's sealed properly when water beads and forms droplets on the surface. Then have it sealed again a year later — perhaps during spring cleaning season? After that, you'll just want to make sure you wipe up accidental spills as soon as they happen.
Your Dishwasher
To ensure this heavy-duty cleaning appliance gets all the tomato sauce stains off of your dinner plates, you have to clean it too. First, remove any bits of food on the bottom. Then, run a cycle with a specialty cleanser made for your dishwasher about once a month.
