Tide is designed to provide exceptional cleaning and whitening, along with our Ultra Oxi technology that is designed to provide long-lasting freshness. Some tips to get the best results with your detergent are: be sure to not overload the washer, and to use the recommended amount of detergent for average water hardness, a little more in very hard water, a little less in very soft water. Also sort clothes by color and fabrics so that you can use the hottest water that is safe for the fabrics, and use the correct was cycle for the types of fabrics you are washing together. If you notice stains before washing, try pre-treating them. We appreciate you reaching out, and would like to help you further. Please give us a call Monday through Friday, between the hours of 9:00am to 6:00pm EST, at 1-800-879-8433 for additional assistance. -The Tide Team
