Clean spills, including water, immediately by blotting with a clean sponge or cloth.  Avoid exposure to all liquids. Professional cleaning recommended.  Appropriate rug pad is highly recommended on all surfaces to prevent slipping, add cushion, and improve durability.  For vacuuming, use a vacuum cleaner without beater bar or one where you can set the bar to the highest pile setting.  If your vacuum has variable power settings, set on low.  Vacuum full length of the rug, turn and repeat to the next area, rather than back and forth motion.
