We love Charlie's Soap. I have 2 active boys, 2 dogs and love to garden, Charlie's Soap cleans clothes, cloth diapers... even in cold water. I have a HE washing machine and no problems, If you go there website www.charliesoap.com they have all their info. The've also recently switch to cloth bags instead of paper. So even in the HE machine I still use the powder, I also recently purchase the all-purpose cleaner to try out. Also, there is no perfumes or dyes so for kids and people with chemical sensitivity or allergies it's great.
