When your shower head starts shooting water in all directions or the water is barely coming out of your shower head, then you know there is limescale buildup that you need to clean out. Some shower heads are easy to remove from the shower arm while others you will need to clean while still attached to the wall. Follow these steps below to start getting a steady flow of water for your next shower.
Unscrew the shower head from the shower arm using a wrench. Wrap masking or electrical tape around the shower head where you will be using the wrench to protect the finish.
Submerge the shower head into a container of one part vinegar, one part water. Make the vinegar/water mixture deep enough to completely cover the shower head. Soak the shower head for at least three hours. If the limescale is thick you should soak it overnight.
Remove the shower head from the vinegar/water mixture and rinse with clean water. Check for any stubborn limescale deposits left behind.
Poke a toothpick through the holes of the shower head to remove any limescale deposits. Use a toothbrush to remove limescale from the outer surfaces of the nozzle.
Reattach your shower head to the shower arm on the wall and test the water flow. Repeat the process, this time using more vinegar and less water, if the limescale is still causing an interruption in flow.
Get a sturdy plastic bag with no holes in the bottom and fill it with one part vinegar and one part water. Make sure the mixture is deep enough to completely submerge the nozzles of the shower head.
Wrap the rubber band around the top of the bag two or three times since it will be much more difficult to get the rubber band around the bag with the shower head and vinegar/water in it.
Attach the bag to the shower arm with your large rubber band (or any method you choose to keep the bag tightly around the shower head for several hours), submerging the shower head in the vinegar/water mixture. Let it soak for at least three hours, or overnight if the limescale is very thick.
Remove the bag and the vinegar/water mixture from the shower head and run the water to check the water flow.
Use toothpicks and toothbrushes to remove any residual limescale deposits from the holes or surface of the shower nozzle.
