This detergent seems to get the job done.  I've used it on towels, stinky gym clothes, and everyday wear.  I like the fragrance but it may be a bit too feminine for some male tastes.  The concentration is good and it doesn't take much for a full load.  Easy to handle, no drip cap, I would buy it again.

Mrs. Meyer's has good cleaning power and it leaves my towels quite soft. I haven't tried it on anything exceptionally dirty but it certainly does the trick on every day wear and tear.
