Thank you for viewing my product! This is OxiClean, a Costco staple. It's useful for various household stains on clothing, fabrics, kitchen areas, water areas, furniture, and more. It uses the power of oxygen to remove stubborn stains and even eliminates odors. - For regular clothes (white and colored items), simply add it directly to the washing machine! - For clothes with stubborn stains, soak them. - For stains on carpets, make a solution and apply it directly to the stained area, then wipe it off after 1-5 minutes. - Make a solution and apply it to the tiles in the entryway or bathroom, then lightly scrub after 5-30 minutes. I purchased this at Costco and have stored it unused. Please note that I will ship it with the shipping label attached directly to the outer box. I will do my best to accommodate price negotiations! Feel free to ask in the comments! It's stored at home, but I've kept it carefully, so please rest assured. Also, please understand that this is a personal sale. I will ship it promptly after confirming payment. If there is a delay in shipping, I will send you a message to let you know. Thank you. My shop's product list ↓↓ #yasutaro
