I own two dogs and as any dog owner will tell you that keeping your carpets clean and allergen free is a major concern. With this in mind I wanted to make sure that all the materials used to clean my carpets were safe and non toxic. The crew from Cityclean were very responsive to my desires to have both clean carpets and provide a safe environment for my pets. ""Thank You"" Cityclean. You did an excellent, professional job in a relatively short amount of time and would not hesitate in recommending you to friends and colleagues.
