Unscrew the base of the shower head where it meets the pipe. Lefty-loosy. You can dunk the head in a container of CLR to clean off the calcium. Also you can ***** them off using a small pin. If your head has rubber nozzles, you can just rub the head while the shower is on to clean them.

firstly clean all the shower holes with a needle tip. you can also apply some descaler on the shower. Cut an old cycle tube piece round to the size of shower head. Make a hole in the centre of the cutted piece.Apply some grease on the patch & place it between the shower & head. Tight it up.If there is not enough space for rubber just apply grease on the head & tight it.

Personally, when my shower head gets crappy looking, I soak it in white vinager for the day and it's clean and good as new for my shower the next morning

get some CLR which is calcium lime and rust remover.Unscrew it from the pipe on the wall with the water off and pour it where the water flows into the head and wait for it to drip out the jets.

On the face of the shower head where the water sprays out of ,their should be a threaded nut to unscrew This is called the aerator.This is the part wher the filter screen is .Once you clean this part you should be up and running.

Once you've purchased your new shower head the first step in replacing the head is to make sure your shower faucets are firmly turned off and then remove the old shower head. If you look at the existing shower head, you'll notice flat spots on what's called a pipe nipple at the base of the shower head where the head screws into the goose-neck pipe that sticks out of the wall. * Take an adjustable wrench and tighten the wrench onto the base of the shower head flat spots. * Turning counter-clockwise, loosen and remove the old shower head. * Clean the threads on the goose-neck of any debris such as old pipe compound or Teflon tape.
