I also use the Vinegar / Dawn Blue for my tub/shower and the sinks ... absolutely amazing. I also came across a great cleanser made by adding the peels of 2 oranges or grapefruit to a mason jar, filling it with white vinegar. Keep it tightly sealed for 2 weeks before using. The post stated it's a great household cleanser and that it take the old iron stains off of sinks, toilets, etc. I haven't tried this one yet, but plan to.
A cousin recently shared that she uses the Vinegar and Dawn on her stove top, and wipes it down with a Bounce dryer sheet. Dryer sheets are not exactly natural though .... she did say that it takes all the grease and old sticky oil spots off that most commercial cleansers do not.
Would love to talk to you re: the SCD diet ..
