Use protective items such as coasters, trivets, and placemats under glasses, hot dishes, china, and plates to prevent annoying stains and scratches.
Make use of a rug/mat at entry areas to prevent normal foot traffic from getting into as much dirt/sand; it kind of catches it.
Quick dusting and cleaning should be performed regularly, and deep cleaning should be done periodically.
Always use a neutral pH cleaner when cleaning all stone surfaces—don’t ruin the finish!
If there is a spill, clean it up right away; that’s really the way to reduce damage over time.
To cut down on soap scum, squeegee the stone shower walls after each use. It helps a lot.
Use a terry cloth or microfiber towel when you are cleaning; don’t use anything else.
DON’T:
Do not let acidic or alkaline substances be in contact with stone surfaces. This is not a complete list of vinegars, wines, or lemon juice. A bit of “just a little” can make for a faded track.
Avoid using green or brown scouring pads. Even if it appears to be very soft, the grit in those pads could actually scratch the hardest-looking stone.
Avoid using nail polish, hair color, or hair spray near the stone. Some of those chemicals will stain and possibly etch before you can even see them.
Avoid putting perfumes, aftershaves, or wet bottles down on bathroom counters. Store cosmetics and perfumes in their own containers and clean up any spills.
Avoid sliding heavy items over stone floors. Do not slide, scrape, or use a felt pad to pick up.
Don’t leave water accumulating around sinks. The stone will be gradually broken down by the standing water. This is also true if plants are placed on top of countertops: water can seep into the surface and form persistent stains.
Avoid cutting directly on granite or other natural stones and use a cutting board.
Don’t use dish soap, vinegar, bleach, ammonia, or general-purpose cleaners. Also, avoid using bathroom, tub, or tile cleaners.
