No enzyme cleaner ingredients, means it won't work well on sweat, oil, food, stains, etc, and won't work well in cold water. And it doesn't have an oxygen bleach.

Yes it is.. "Pros: Highly effective for everyday dirt, leaves no soapy residue, safe for septic systems, and comes in reusable/recyclable metal tins rather than plastic jugs.
  • Cons: Because of its simple formula, it may struggle with heavy stains or grease."

Roughly 7 years if you do 2 loads per weekend.
5 years if you do a 3rd load for bedding etc.
