Carpets that are going to remain should be repeatedly cleaned with a carpet shampooing machine to remove all traces of contamination. It may take several attempts to completely clean a carpet, and to prevent new urine and faeces being deposited during the cleaning process, specific areas of carpet can be protected by covering them with heavy polythene sheeting.
