It is hard to find dish detergent that is 100% natural, so I opted to make and try some homemade detergent to see if it worked just as well as my pods. I used a mixture of two recipes to make scoop-able lemon scented detergent. You can find the recipes here and here.
The verdict? It worked pretty well. The only dishes that were not clean were those that had not been pre-washed in the sink (i.e. P’s chocolate protein shake cup left in the sink for 4 days growing crusty).
Update (9/6/16): Our roommate forgot to put the lid on the container, and all the contents went hard! It was still usable, but a hassle to fish out each time. Make sure yours is in an airtight container and always sealed.
