Advantage of washing carpets
At high exposure over several years however, normal vacuuming is no longer sufficient. If heavily soiled, a carpet wash is recommended for maintaining the value. As of ten years of use it is even recommended - but should always be done by an expert.
During a professional cleaning process persistent stains and dirt are simply flushed out. Even damage caused by water or fire can be alleviated or completely eliminated through professional treatment. Moth protection can eventually be incorporated following the wash.
