Found an amazing new way to clean my sink.

I have a lot of hard water, not only in the sink, but that leaves a film on dishes that leads to food residue buildup and is just a nasty mess. I have been trying to find a new way to clean that sink because my family and I are trying to cut back on spending money. We were spending $20-$30 a month on name brand dish soap and I decided that I could do that better and cheaper. So I took 2 cups of warm water, 1/2 cup of white distilled vinegar, a tsp of clay powder (bentonite), 1 tsp of washing soda and 1 tsp of liquid dish soap and mixed it all together and put it in a spray bottle. This left 1.5 Tbsp of washing soda and 1 Tbsp of clay powder left over. I then scrubbed my sink really well with a scrub brush and then used a microfiber cloth with some of the extra powder and scrubbed really well. Then I just sprayed and wiped the whole sink down in about 5 minutes. I have never been more satisfied with my sink in my life for so little money and effort. I might be only a 25 year old man who doesn't clean often but this is great for the kitchen sink. Thank you.
