well, my detergent has congealed so i will mix some with water in a smaller container and try it out today! i did find out that it is better to add the lavendar (or other type) essential oil only when you refill your smaller container with the half concentrated detergent/half water. just put about 10 -15 drops drops in (or more or less if you like) for every 2 gallons you keep on hand, rather than adding the essential oil straight to the concentrated solution. i'm not sure why...it may be okay to add a larger amount of oil straight to the concentrated batch. i added some to the big solution yesterday when mine was starting to congeal, but not very much, so i'll add a little bit more to my refill bottle when i go to make it. just wanted to let you know in case you decide to make some, too!
also, i'll try to post a food recipe today or tomorrow:).
