I switched to this product after my son was born. Instead of buying two detergents I would wash my clothes in it as well. After a few months I started noticing that my clothes did not look clean but dingy. My son and I both have sensitive skin and I noticed that we both had small rashes. When I switched back to Arm and Hammer the rashes disappeared and our clothes did not look dingy. A friend of mine had the same experience as I did.
