Over time, calcium and magnesium from evaporating water harden into a crusty white or green buildup around the edges and crevices of the handle. Tackling this buildup requires patience and the right method rather than aggressive scrubbing, which can scratch the finish.

Clear a small workspace near the shower, and place a towel in the bottom of the tub to catch any small parts that might slip from your fingers during the process.

Remove the handle carefully

Turn off the main water supply to the bathroom if you are worried about accidentally turning the water on, though this is usually unnecessary for simply cleaning the exterior handle. Look closely at the faucet knob to find any hidden fasteners. Many modern handles feature a small decorative cap in the center that pops out to reveal a screw holding the knob to the stem. Pry this cap off gently using the tip of a flathead screwdriver or the edge of a plastic card to avoid scratching the surrounding finish.

Once the center screw is exposed, hold the handle steady with one hand and turn the screw counterclockwise to loosen it. Set the screw aside in a safe spot, such as a small bowl or cup, so it does not roll down the drain. Gently pull the handle straight out toward you. If the knob feels stuck due to accumulated mineral deposits, wiggle it gently from side to side while pulling. Avoid using metal pry tools against the wall or the escutcheon plate behind the handle, as this can crack tiles or mar the wall surface.

Soak the parts in a cleaning solution

Place the removed handle and any associated decorative trim pieces into a container or basin. Pour enough white vinegar over the components to completely submerge them. Vinegar contains acetic acid, which naturally dissolves alkaline mineral deposits like calcium carbonate without harming most standard plumbing finishes, including chrome, brushed nickel, and brass.

Allow the parts to soak undisturbed. Light buildup may loosen within half an hour, but heavy, aged crusts require several hours of soaking to break down thoroughly. If the knob is attached to a large wall plate that cannot be easily removed, or if you prefer not to take the handle completely off the valve stem, you can still use the vinegar method. Saturate a clean cloth or paper towel thoroughly with vinegar and wrap it securely around the handle and base. Secure the soaked cloth with a rubber band or twine to hold it tightly against the dirty surfaces, and leave it in place for an hour or two.

While the handle is soaking, take a damp cloth with a drop of mild dish soap and wipe down the exposed valve stem and surrounding wall area. Soap scum and mildew often accumulate in the hidden gap between the handle and the wall. Cleaning this area ensures that when you reinstall the clean knob, it will not immediately rest against old grime.

Scrub away softened residue

Remove the knob from the vinegar bath after the soaking period is complete. Take your soft-bristled brush and begin working around the contours, grooves, and undersides of the handle. The mineral deposits should now have a softened, chalky consistency.

If patches of white crust remain, repeat the soaking and brushing steps until the entire surface is completely clean and smooth to the touch.

Dry and polish the surface

Take a clean, dry microfiber cloth and thoroughly dry every part of the faucet knob. Leaving water droplets to air dry on metal fixtures invites new mineral spots to form almost immediately, undoing the work you just completed. Buff the surface gently with the cloth to restore its shine. For polished finishes, a dry cloth works well to bring out a clean reflection, while brushed finishes benefit from wiping in the direction of the grain to maintain an even appearance.

Check the small screw and any decorative caps you removed earlier. Dry them completely as well. If the screw threads show signs of corrosion or stiffness, a very light touch of petroleum jelly or plumber's grease can help lubricate them for easier reinstallation and future removal.

Reassemble the shower fixture

Align the handle with the valve stem in the same position it was in before removal. Push the knob straight back onto the stem until it sits flush against the trim plate or wall. Do not force it; if it does not slide on easily, check the alignment of the internal splines or flats to ensure they match the orientation of the stem.
