Rinenna Laundry Detergent According to the manufacturer's description, this detergent focuses on stubborn stains caused by sebum and bodily waste. It uses a generously formulated protein-degrading enzyme to effortlessly clean away sebum stains that accumulate on clothing over time. This versatile detergent is suitable for baby clothes, cloth diapers, cloth menstrual pads, absorbent underwear, and removing blackening and yellowing from shirt collars. It can also be used on accumulated stains on pillowcases, bedding, and bath towels, which should be kept clean for healthy skin. I don't remember when I purchased these, but they have been stored on a shelf. They are in home storage, so the boxes may not be pristine, but the product is unused and the seal has not been opened. I am selling a set of two boxes.
