Carpets are an environment in which bacteria and allergens will remain for a long time without thorough cleaning, meaning that not only are professional carpet cleaning services required for appearance’s sake, but for health and hygiene reasons, too. It is recommended by manufacturers and professional bodies that carpets should be cleaned by a professional cleaner every 12 months and more often, if they’re in a home with small children and/or pets, or if its in a commercial space or office.
