How To Make It:
1 cup rubbing alcohol
1/4 cup white vinegar
(It may be diluted with water if you'd like a gentler formula)
Mix together and either store in a spray bottle or dab onto a stain with a cloth. Let soak if necessary and rub out with an old rag. And, of course, test in an inconspicuous place to make sure no discoloration occurs.
***As superb as this cleaner is, it is not to be used on painted surfaces--you might end up with missing paint on your walls***
