When we opened it, it stunk. We washed it with dish soap and that didn't help. Then we tried soap nuts. We threw 4 soap nuts in a jar of cold water and shook it up. They made a lot of suds. Then we poured the liquid in the cooler and washed it out, and like magic the cooler smelled fresh & clean. Not even a hint of the bad odor. Green Virgin Soap Nuts work great in all water temperatures. For cold just wash as normal. There is no need to soak the nuts in hot water and then throw the water in the washer. Ours work great in cold water. Just like with chemical detergents some stains will need prespotters and whites will come out whiter with bleach. But you will never need fabric softener or dryer sheets again. If you want a scent in your clothes use essential oil. Just sprinkle a few drops on a sock in the dryer. Buy Green Virgin Soap nuts. You'll save money. You'll help clean up the environment. Your clothes will last longer & your towels will be more absorbent. And most important you & your family will feel better & be healthier.
