Windex for Mildew Control

Fighting mildew can be a problem for most boat owners and I really hadn’t found any miracle way to clean it up. I was reading a book “Take the Mystery Out of Boat Maintenance”. The author says ‘There is a product that removes mildew easily-Windex!”.
The author recommends using it in its off the shelf form with no additives. He goes on to say:
“The secret is knowing how to use Windex. Spray a generous amount of Windex on the moldy or mildewed seam or area, but do not wipe it off. Let it stay WET for about ten minutes (spray more if necessary). In ten or fifteen minutes, the undesirable substance will either bubble to the surface or will be ready to be wiped off with a paper towel or rag. On particularly stubborn areas, scrub with a toothbrush after the ten minute waiting period, and then wipe it clean”. He goes on to say that “it harms NOTHING” (won’t effect your boats finishes).
I plan to test this out in the spring after I untarp “Feather”.
