I have over 37 years in the service industry, and have been using the dry compound cleaning system on residential and commercial carpeting in Washington, DC, and surrounding areas, for over 20 years. My mission is to provide the best possible value and service to customers. I have seen nearly every type of problem when cleaning carpets and our Dry Extraction System is the most effective method I have ever seen. You must be satisfied or it's free! In fact, I will clean your carpet just as I would my own mother’s. The EPA recommends a schedule of regular carpet cleaning to reduce and control allergens and toxins in your indoor environment. Poseidon’s Dry Extraction System will dramatically reduce dust mites, mold, bacteria, pollution, viruses, pollen, dog and cat dander, oils, hair and saliva residues. We will eliminate food and red wine stains, pet stains (recent and old), blood, vomit, urine and just plain heavy soil.
