The best and foremost step in maintaining your rugs or carpets is just a doing a good vacuuming on them. The beauty of rugs and carpet is that they can hold dry particulates and keep them away from our breathing zones, but the not so beautiful part about them is that they can hold dry particulates. Vacuuming keeps the sandy grit from scratching the fibers.
The question we get very often is “what type of vacuum do you recommend?” First of all, nothing beats the efficiency of a beater bar. Granted, there are certain rugs such as flat weaves, certain loop carpets that have a tendency to pull tufts, but a beater bar can break the weak bond the soil has on the fiber and sweep it up into the vacuum tube much better than just a suction vacuum.
If you have area rugs, periodically turn the rug upside down on the floor and vacuum the back with the beater bar. You will notice once you turn it back over that the floor will have some sand on it. Sweep it up, and then vacuum the face of the rug. That sand is what is buried deep into the base of the rug.
Finally a little tip. Everybody knows not to vacuum fringes for obvious reasons. But many will use the powerhead (beater-bar) of the vacuum over the fringes working outward so the carpet fringe doesn’t get caught. Some reason that this is a good way to groom the fringe. However, using a powerhead will gradually weaken the cotton (or wool, or silk) and the fringes get smaller, thinner, or even completely disintegrate. So, it’s best never to vacuum the fringes.
