The ingredients are the same (acetic acid) except the Indicator version
adds an indicator.  The dilution may be different depending how you use
it and the concentration in the bottle (I don't know if Indicator is 28%
or something different, I think it is more concentrated because if I'm
remembering right, you use less of it in the final dilution).
