New Refill Pack Set of 5 I am selling these because I bought a lot of them to take advantage of a point promotion. These are the purple NanoX. The purple one is recommended when you are concerned about odors. To use Top Super NanoX, use about half the amount of the conventional product (Top Clear Liquid) to wash thoroughly. When applying it, place a towel or something similar between the fabric and the washing machine to prevent the undiluted solution or dirt from getting on the fabric or washing machine. ● If stains are difficult to remove, repeating "apply for 12 hours → wash" is effective.
