these tiny bud vases yesterday, the problem of cleaning them was pointed out by a practical-minded reader. And it's so true - many an intricate vase is fine and dandy until it's time to clean it. So, what to do? Before you pull your pipe cleaners out, check out these methods for cleaning vases with hard-to-reach interiors: The Sand Method: Put a little bit of sand into the vase. Add warm, soapy water and swirl it around thoroughly. The sand will scrub the vase interior and the soapy water will help loosen grit and stains from the surface. Rinse thoroughly and repeat as necessary, then allow the vase to air dry. The Cola Method: This one really threw us for a loop. Coca Cola can actually be used to scrub surfaces that you can't reach to scrub by hand. The fizzing will "scrub" the vase interior. Just fill the vase about half way with cola, swish it around, and let stand for several minutes. Rinse well (really well) and air dry. We've read that the same can be done with denture cleaning tablets or Alka-Seltzer. We can't wait to try one of these methods on our Tall Ribbon Vase from MoMA. That thing has not looked clean since the first few times we used it almost a decade ago! We'll bring you the results as soon as we give it a go. Do you have a hard-to-clean vase in your home? How have you handled cleaning or do you, like us, just skip over that particular vase when you're putting flowers in water?
