Hopefully this helps someone out. I have a couple bottles that don't have the markings for dilution ratios. I hate having to sit their and figure out how much for how much??? So I made a chart for the common size bottles or containers you may encounter. There is a pretty simple formula at the bottom of the page if you have a special size container you would like to use. It's in excel so you can change what format you want the ounces needed to. I don't know if there is already one here, if so, here's another one. If not, hope it helps you out.
