I have to admit that if forced to choose between Charlie's or Micropak for my mf cleaning, I think I'd go with Micropak. However, I haven't included the APC in my laundry yet. I've only used it for around the house and found it to be quite effective.
One fear of mine is that I have to share the washing machine(s) with others because I live in a condo and goodness knows what they use for their laundry. I can't help but think that there are remnants of their detergents in these machines that would adversely effect my towels when I do my wash.
