Shower heads are frequently some of the most infectious items we can possibly be in contact at home. The hot and humid environment is ideal to grow bacteria, some of it potentially harmful. If you notice your shower head is dirty and full of scale, its time for a clean:
Use a solution of water and vinegar in a bucket and leave your shower head soaking in it overnight. It should be clean the next morning, just rinse it with water and you are done.
