Carol, I don't know why it would not be suitable. It is not any kind of a solvent and it is non-abrasive.
Cheryl, I am using equal amounts of white vinegar and rubbing alcohol. I really think that all the rubbing alcohol does is make the solution evaporate more rapidly from floor surfaces. Typically, windows will be gone over with a dry cloth/paper anyway, so evaporation is not important there. Oh, perhaps the alcohol would also kill some bacteria/viruses on surfaces. I don't know whether it would remain long enough to do this though.
