Not a great picture, but you know the stuff that accumulates around the faucets. Eeeewwww!! I soaked a paper towel in regular old white vinegar and put it all the way around the bottom of my faucet, where it touches the counter top. I let it sit for a few hours. When I came back to it, all the goop just wiped right off. Just like magic!!
I've also soaked my shower heads in baggies of vinegar (attached with rubber bands) to have them come out so great that the water actually shoots straight.
This website has lots of other great uses for vinegar.
Yesterday my shower was draining very s l o w l y. So gross. I didn't want to run to the store for Draino and frankly that stuff even scares the chemical loving me. So I googled it and found this recipe for drain cleaner: 1/2 cup baking soda, 1/4 cup salt, 1/2 cup of vinegar, and boiling water. So I mixed the baking soda and salt and put them into the tub right near the drain. Then I poured the vinegar over the top. It's so cool to watch it bubble. After waiting for a few minutes, I then poured about 4 cups of boiling water down the drain and left it. A couple of hours later when I went to shower it was draining normally. Yay!
