Shower heads in Toronto's hard water areas get clogged with calcium and mineral deposits over time. The spray holes clog, water pressure drops, and the head sprays unevenly. Vinegar dissolves mineral build-up without chemicals.
Method 1: Plastic Bag Soak (Without Removing the Head)
- Fill a zip-lock or plastic bag with enough white vinegar to fully submerge the shower head face
- Secure the bag around the shower head with a rubber band so it stays submerged — make sure all the spray holes are underwater
- Leave for at least 1 hour for mild build-up, or overnight for heavy scale
- Remove the bag and run the shower on hot for 1–2 minutes to flush out loosened deposits
- Scrub remaining deposits from the spray holes with an old toothbrush
- Run the shower again to clear
Method 2: Remove and Soak
- Unscrew the shower head from the arm — wrap a cloth around the connection to protect the finish, and use adjustable pliers if needed
- Submerge the entire head in a bowl of white vinegar
- Soak for 1–8 hours depending on build-up severity
- Scrub with a toothbrush, paying attention to spray holes
- Use a toothpick to clear any individually clogged holes
- Rinse well and reattach — wrap the threads with plumber's tape before reattaching to prevent leaks
How Often
Every 1–3 months in hard water areas, or whenever you notice reduced pressure or uneven spray. Toronto's water is moderately hard, so quarterly cleaning is a good baseline.
Tips
- Do not use vinegar on gold, brass, or nickel finishes for extended periods — it can damage the coating. 30 minutes maximum for these finishes, then rinse immediately
- For chrome finishes, overnight soaking is fine
- If build-up is very heavy and vinegar alone isn't cutting it, try CLR (Calcium Lime Rust) remover — follow product instructions for dwell time
- A weekly quick spray of daily shower spray on the head after showering prevents build-up between deep cleans
