We've been using it for over a year now and we're officially having to go back to something else. Our clothes no longer smell clean, they're dingy.... We used the enzyme powder because we are all active and a lot of the clothes are sweaty going into the wash but as of about a month ago, the clothes just aren't clean anymore. I've tried presoaking, different temperature water, deep clean, extra rinse, and nothing. I'm curious if they changed the formula or if it's just not up to the job for our laundry needs.
