How about save money while doing your dishes as well? Yes, lately I decided to experiment and make my own home cleaning supplies and was amazed by how many recipes and how to´s are available on the internet.
As for me I rather have something simple and with not many ingredients on. Most recipes I found had so many things to add that I could not even remember what and for what it was at the end. Mostly I use just baking soda on my dishwasher, and a single teaspoon is enough to do the job. This time, I decided to experiment mixing Washing Soda, Borax, and Kosher Salt. I haven´t noticed any difference between using this mix to just Baking Soda. And to avoid that any residue is left on my dishes I add White Vinegar at the Rising compartment.
So here you have it in just a couple bucks. Dishwasher soap and Rinser that works pretty great!
