Remove the shower head and soak it in a bowl filled with equal parts warm water and white vinegar for thirty hours. Afterward, scrub away any loosened buildup with an old toothbrush and rinse it thoroughly before putting it back.

To clean a mouldy shower head, detach the fixture and submerge it in a mixture of white vinegar and warm water for several hours to break down the fungal growth. Afterwards, scrub the remaining residue away with a stiff brush and rinse thoroughly before reinstalling it securely.

Mould thrives in damp, warm environments, making the bathroom an ideal habitat. The constant moisture and lack of ventilation create conditions where fungal spores easily settle and multiply. Over time, these spores accumulate inside the internal chambers and along the exterior nozzles of the shower head. When the water runs, it can aerosolize these spores, releasing them into the air where they may affect indoor air quality. Addressing this problem requires a systematic approach that reaches both the visible exterior buildup and the hidden internal deposits.

You will need a pair of adjustable pliers, a soft cloth, a stiff-bristled brush, and a basin large enough to submerge the shower head. If the fixture is made of metal and you plan to use pliers to loosen the collar, wrap a piece of thick cloth or rubber around the connection nut first. This prevents the metal jaws of the tool from scratching or gouging the finish.

Turn off the water supply to the shower to prevent any accidental leaks while working. Grip the connecting nut that attaches the shower head to the supply pipe. Turn the nut clockwise if you are facing the wall, or counter-clockwise depending on the specific alignment of your plumbing, though the standard rule of righty-tighty, lefty-loosey applies when looking at the nut head-on. Gently loosen the nut until you can unscrew the remainder of the fixture by hand. Be careful not to lose any small rubber washers or mesh screens located inside the joint, as these are necessary to prevent leaks when you put the fixture back together.

Soak the Fixture in a Cleaning Solution

Once the shower head is detached, place it inside your basin or bucket. Fill the container with enough plain white vinegar and warm water to completely submerge the entire fixture. The acidic nature of the vinegar helps dissolve the mineral scale that often traps mould spores, while also targeting the fungal growth itself. Ensure that the water is warm rather than boiling, as extreme heat can warp plastic components or damage rubber seals.

If your shower head cannot be easily removed from the wall due to stubborn plumbing, you can fill a sturdy plastic bag with the vinegar solution, secure it tightly around the fixture using a rubber band, and leave it hanging overnight so the nozzles remain immersed in the liquid.

Scrub the Exterior and Internal Channels

After the soaking period is complete, lift the shower head out of the basin and discard the spent liquid. You will likely notice that much of the dark staining and crusty buildup has already softened or dissolved. Use a stiff-bristled brush to scrub the exterior surfaces, paying close attention to the spray nozzles where mould tends to cluster.

To clear the internal channels and individual spray holes, use a thin, flexible tool such as a wooden toothpick or a straightened piece of wire. Gently insert the tool into each individual hole to push out any remaining debris, scale, or mould fragments that the soaking process loosened. Avoid using excessively thick metal needles or nails that could stretch or deform the rubber or plastic nozzles, altering the spray pattern of the water. For fixtures with adjustable spray settings, cycle through the different patterns while scrubbing to expose hidden internal chambers to the brush and running water.

Once the fixture is entirely clean, dry the exterior with a soft cloth to prevent water spots from forming on the metal finish.

Reinstall and Test the Shower Head

Before putting the fixture back onto the supply pipe, inspect the rubber washer and any mesh screen located inside the connection joint. If the washer appears brittle, cracked, or compressed flat, replace it with a new one of the exact same size to ensure a watertight seal. Wrap a small amount of thread-sealing tape clockwise around the male threads of the supply pipe if the manufacturer recommends it, though many modern fixtures rely solely on the rubber washer to prevent leaks.

Thread the shower head back onto the supply pipe by hand, turning it gently to ensure the threads catch properly without cross-threading. Once it is hand-tight, use your pliers with the protective cloth wrap to give the connection a slight additional turn, being careful not to over-tighten and crack the plastic or metal nut. Turn the water supply back on and let it run for a minute or two. Check the connection point at the wall for any drips, and observe the spray pattern to ensure water flows evenly from all the nozzles.

Wipe down the wet surfaces of the shower enclosure regularly, including the walls, glass doors, and the shower head itself, using a dry towel or a squeegee. Reducing the amount of standing water and residual moisture deprives mould spores of the hydration they need to germinate and grow. Additionally, spraying the shower head lightly with a vinegar solution once a week and wiping it down can stop fungal colonies from establishing a foothold, keeping the fixture clean and functional for a long time.
