Granite's natural beauty, durability, and infinite variety of patterns and colors make it the most sought-after and elegant of countertop materials. It and other natural stones are some of the easiest materials to maintain and, with proper care, will stay new looking for years.

Clean spills on granite surfaces immediately to minimize any damage Use mats under china, ceramics, silver, or any item that may scratch the surface Use mats or trivets under hot dishes or pans Use coasters under all glasses, particularly those containing alcohol or citrus juices Do not wait to clean up spills Never cut directly on the surface Do not use cleaners containing acid or bleach Do not use abrasive cleaners such as dry cleansers, scouring powders, or 'soft' cleansers Do not use vinegar, bleach, ammonia or other general-purpose cleaners

Other than gentle cleaning, all you need to do is reseal with a penetrating stone sealer at least every year or two to prevent staining.  This type of sealing is standard for granite slab, tiles, or any other natural stone such as marble, travertine, or slate.
 
Sealing
Granite, like all natural stone, is porous and must be sealed with a penetrating stone sealer after installation. This will protect the granite from staining or scratching and will also maintain the beautiful shine.

• Seal with a penetrating stone sealer, such as Benissimo Stone and Grout Sealer
  
  
• Periodically reseal (1-2 years, depending on wear) as routine maintenance

Cleaning
Use a cleaner recommended for granite stone, such as Benissimo Granite Revitalizing Wipes, that will gently and safely clean while sealing and protecting the granite.  Always use a neutral cleaner with a pH between 7 and 10.
