Toronto's water supply has significant mineral content (calcium and magnesium), which leaves scale deposits on shower head nozzles over time. The result is reduced water pressure, uneven spray patterns, and nozzles that spray sideways instead of forward. The fix is a vinegar soak — it dissolves mineral scale effectively without any special products or tools.
The Bag Method (Easiest — No Removal Required)
This method works without removing the shower head:
- Fill a plastic bag with enough white vinegar to fully submerge the shower head face
- Secure the bag around the shower head with a rubber band or zip tie — the nozzle face should be fully submerged in the vinegar
- Leave for 1–3 hours (overnight for heavy buildup)
- Remove the bag and run the shower on hot for 1–2 minutes to flush loosened deposits
- Scrub remaining deposits from the nozzles with an old toothbrush
For chrome or nickel-finished shower heads: limit the vinegar soak to 30 minutes to avoid finish damage. For stainless steel or plastic: longer soaks are fine.
Removal Method (For Heavy Buildup)
If the bag method doesn't fully restore flow, remove the shower head for a full soak:
- Wrap the shower arm fitting with a cloth to protect the finish and unscrew the shower head (counter-clockwise) using an adjustable wrench
- Submerge completely in a bowl or container of white vinegar
- Soak for 2–4 hours or overnight
- Use a toothbrush to scrub the nozzle face
- Use a toothpick to clear any individually clogged nozzles
- Rinse thoroughly under running water
- Reinstall with thread tape (Teflon tape) on the threads if the existing tape has degraded
How Often to Descale a Shower Head
- Vinegar bag soak: every 3–6 months
- Earlier if water pressure noticeably drops or spray pattern becomes uneven
