Well heck, if distilled white vinegar will do it, a high-dollar Italian Balsamic is bound to be better, right?
I know you posted that as a joke, but there's good reason to use only distilled white vinegar. For one thing, it's not sticky...but the more important reason is, it's more acidic which makes more effective in preventing mineral buildup. Although it is possible to use vinegar to dissolve buildup in hoses, it's way too labor intensive compared to muriatic acid or products specifically made for that purpose. People who claim it doesn't work make the mistake of just letting something soak in it for hours even days...not realizing that it exhausts itself and has to be replaced every couple of hours. As is true of most things, prevention--a cupful or two every week or two--is a whole lot cheaper and easier than cure.
