With proper annual re-sealing, granite is very resistant to stains. Minor scratches or dings in granite can be filled in with color-matching epoxy or resin. Quartz is a nonporous material, which allows it to repel coffee, oil, and even food coloring without sealing, however, For you should be careful about not spilling lemon juice, vinegar, wine, or cut any acidic fruits and vegetables like tomatoes and pineapples directly on the countertop. You should also be careful of common household cleaners, which can be very acidic as well. Most sealants won’t prevent etches, and those that do tend to change the finish in a way that most don’t find appealing. With that said, always use specially formulated cleaners on your countertop, always use a cutting board, and make sure you clean up any spills ASAP or they can leave an etch faster than you may think!
