Most people may not pay close attention to their showerheads when they clean the bathroom. Over time, grime and gunk build up on your shower head after every shower you take. To clean your shower head, grab a sandwich or Ziploc bag, rubber bands, and white vinegar. Add white vinegar to the bag and then wrap around the showerhead. Let it sit for a few hours and then you can take off the bag. If there is leftover residue, simply wipe clean.
