Vacuum Regularly
The number one way to ensure rug integrity is vacuuming. Vacuuming regularly helps prevent dirt on the surface of the rug from filtering down into the pile where it can accumulate and cause increased wear. Vacuum once a week for a light traffic, one to three times a week for moderate traffic, and daily for heavy or pet traffic. Occasionally, on a hand knotted rug vacuum the back of the rug to remove the fine grit that may damage the foundation of the rug.
Be Aware
Many of todays vacuums are high powered and standard vacuuming can pull threads through the rug backing. Vacuums equipped with a power brush create a raking effect on the rug and can weaken the knots and threads. Ideally, use a canister vacuum (or the handheld attachment on an upright vacuum) to clean your rug. Remember, brooms and manual sweepers are just as effective and often a safer maintenance option.
Beater Bars
When using an upright vacuum, disengage the beater bar as this can pull fibers from the rug and cause premature deterioration. If you are unable to manually turn off the beater bar, set the vacuum to its highest setting.
Shag Rugs
Avoid vacuuming shag rugs entirely as traditional vacuuming can severely damage the rug fibers. Instead, shag rugs should be carried outside and beaten to loosen the dirt and release foreign particles. In cases the shag rug is to large to be carried outside use the handheld hos attachment of your vacuum to clean.
