Clean calcified faucets / shower heads
We have very limy water here and unfortunately the water spouts of the taps often look white because they are so calcified. I do it this way: just put vinegar in a freezer bag (or any other plastic bag, the main thing it's small). Then I put this bag filled with vinegar under the opening of the faucet and attach the bag around the tap with a rubber. It is of course important to make sure that the opening of the cock in the vinegar "floats". The whole thing I let it work overnight and the next day the tap is lime free. Just try it.
Also with the shower head I use vinegar. I fill a slightly larger vessel with vinegar until the shower head is covered with vinegar at the front of the nozzles. Let the whole thing work for a night ... the next day the shower head is clean.
