I do all the time. If it won't come clean with vinegar, I rinse and try scrubbing with baking soda. Baking soda leaves a film on glass, but vinegar leaves everything sparkling and shining, from counter tops to sinks to expensive glassware. I also use baking soda as a deodorizer and help for those nasty set-in carpet stains (test in a small area first). Nothing works better for your money than vinegar and an old toothbrush to get water deposits off of your sinks and countertops. Just spray some on, let it sit until it quits bubbling (or 10 minutes, whichever is longer) then scrub the little spots that escape the sponge around the faucet with the toothbrush, rinse, and repeat if necessary to remove hard water stains. Note that vinegar doesn't remove the green copper stains, however.
