“Attack ZERO Perfect Stick for Indoor Drying” is a stick-type detergent that you put at the bottom of the washing machine without measuring. It is specifically designed for sebum stains and sweat odors, which are the main causes of musty odors from indoor drying, and is effective in powerfully deodorizing and preventing unpleasant odors during indoor drying. The foaming powder targets dirt, and the antibacterial ingredients also suppress the growth of bacteria, making it a recommended product for households that do a lot of indoor drying. Features and How to Use: * No measuring required: Simply take one stick from the bag and put it at the bottom of the washing machine with the laundry (or at the back for drum-type washing machines). * Powerful deodorization: Targets "unremoved sebum stains," the cause of musty odors, and washes away sweat odors and bacterial odors in one go. * Antibacterial and odor prevention: Contains antibacterial agents to prevent the growth of odor-causing bacteria specific to indoor drying and prevents odor return. * Recommended wash cycles: Recommended for use with cycles other than speed courses or quick courses. Recommended for: * Those who do a lot of indoor drying and are concerned about musty odors. * Those who want to easily measure detergent. * Those who sweat easily or have a lot of thick laundry. Points: * "Perfect Stick" is a high-performance detergent specialized for hard-to-remove stains and odors. * If you mainly dry your clothes outdoors, the regular type is recommended, and if you mainly dry them indoors, this indoor drying type is effective.
