Regular vacuuming will hep prevent destructive grit action. Ask us the best type of vacuum cleaner for your vintage or oriental rug and how often it requires vacuuming. Occasionally, you should also vacuum the back of the rug to draw out the very short, light-absorbing bits of yarn that can otherwise dull the luster of the carpet. This operation should be followed by a quick vacuuming of the face of the rug.
