I tried different detergents with Iherb - and liquid and pills, but stopped on the Method. Still, like it or not, they always have the best-laid packaging, just great. This concentrated liquid laundry detergent, placed in a bottle with dispenser. 4-6 zilch in the powder compartment (depending on the amount and degree of soiling) - and all. No loose powders (which are hard for me to breathe and unpleasant), no measuring cap - very convenient. I note another advantage of the laundry detergent Method - it does not require the addition of rinse aid. Somehow, miraculously, it removes static electricity. I rinse often still add the habit, but it ends and I wash without it, the quality does not suffer.
