Thanks to everyone for all the suggestions for replacing dish soap. I now realize there are a lot of options, and I never thought of shampoo. I have those small shampoo bottles saved from hotels when traveling, and I can use those. I hadn't thought of shampoo. Also the suggestion to fill the sink with baking soda and hot water, and also to use those small bottles of gift hand soap - I got a few for Christmas, and will use those. Other suggestions also appreciated.
I did find a you tube video with a simple recipe to shred a bar of soap and stir into 1 gallon of hot water (microwaved) and let it set for 8 hours. I have several bars of soap so I can try that, also. You can add essential oils and 1 teaspoon of baking soda to this recipe, but I don't have essential oils and I am trying to ration use of my one box of baking soda, so I will just use the bar of soap and gallon of water. I will save what commercial dish soap that I have left to use for when I really need to cut the grease after cooking in slow cooker, etc. Also appreciated the suggestion that I water down the dish soap that I have. I hadn't thought of diluting it to make it last longer.
