My wife washed three loads of clothes today and she said she could not tell the difference from using liquid Tide other than the fragrance. The clothes retained a slight Ivory soap scent. No soap residue that we could see on any of the clothes. She did not dilute the batch any further. She also used about a cup of the liquid in a extra large top loader washer. Taking into consideration I made 5 gallons; that would last 80 loads.

Not a bad idea to keep the ingredients on hand.
