In my books (Super Baby Food and The Vinegar Book) they give specific ratios of what to use for certain cleaning surfaces. When I started making my own cleaner I had a few different bottles for all the different things and it was kind of a pain. I shortly came to the conclusion that a basic 1:1 ratio would work just fine in my house. So that is simply what I do. Fill my spray bottle half way with water and top it off with white distilled vinegar. If my kitchen counter, bathroom counters, or tubs need a little extra scrub I simply sprinkle borax or baking soda on them and then spray my cleaning solution and scrub away. I have even used the same cleaning solution to clean my couch. I haven't yet had any problems but do be mindful that you should not use vinegar on granite.
