Ask Dr. Vinny

Dear Dr. Vinny,

I just read the helpful February Wine Spectator cover story, "How to Enjoy Wine." On the subject of cleaning wineglasses, I always wash our crystal glasses by hand and air-dry them, and I’ve always put a squirt of ammonia in the wash water to keep the glasses sparkling. Would that affect the taste of the wine?

—Katie, Gig Harbor, Wash.

Dear Katie,

It shouldn’t, as long as you’re careful to rinse thoroughly. Both ammonia and vinegar (used separately, not together) are effective in cleaning wineglasses that become cloudy from hard-water mineral deposits. If you consistently find your wineglasses cloudy or spotty, you might want to switch from air-drying to hand-drying with a soft, lint-free cloth.

—Dr. Vinny
