The unscented version is my daily driver, and its cleaning performance is excellent with no residual scent left on laundry. It's especially good at removing body oils. Cleaning is comparable to Tide Free and Gentle. It has three enzymes-protease, amylase and cellulase.

I love the perfume of the regular scented version in the bottle but can't use scents in my home.

Thanks littlegreeny. My only beef with Tide Free and Gentle is that I don't feel it rinses well. How does Kirkland compare in rinsing?

It seems to rinse better than Tide Free. And it's definitely better at rinsing than Persil Sensitive. I always run an additional rinse and spin cycle as my washer has an inadequate spray rinse.

We shop regularly at Costo and love Kirkland products. But two different washing machine repair men told me that Kirkland Liquid detergent is particularly bad at gumming up the works inside washers, and that they heartily do NOT recommend it.

I have not used it in many years, so I don't even remember if I ever liked it. I'm just passing on the advice of people who work on washers.
