I received a free sample of the Free and Clear version of this detergent. I wasn't expecting much, to be honest, but I hate to waste anything. I am a bit embarrassed at how short-sighted I was. This detergent cleaned as well as, if not better than, my usual detergent. I pretreat and wash in cool water and I didn't notice any stains left after the wash. A bonus was there was no smell at all! Some detergents I have used had a weird chemical smell even though they claimed to be 100% natural. Also, my entire family has some form of skin sensitivity. I have noticed with some detergents, my kids especially, will get flare-ups. They didn't have any problems after I used this detergent on 2 loads, which is usually how many loads it takes to show me if they have a problem with a detergent. I may try the scented version next to see if my clothes can smell good too. I know I'm asking for it all, good smelling clothes and no flare-ups, but I think if any company can give it all to me it'll be SG.
