As a former professional house cleaner, I would definitely recommend vinegar and water. Safe for any color or composition. Instead of leaving the blinds on the window and trying to clean each slat, I pull my down and "rest" them in the bathtub. Just a cup of vinegar to 3-4" of warm water for about 20 mins in the tub is all you'll need to remove 99% of dust and grime! If you have a handheld shower head, that makes rinsing a breeze. If not, just use a large cup to rinse them with clean water. Good luck!
