Metro Vancouver's tap water is soft, so cloudy shower glass is usually soap scum, not hard-water scale. Warm the glass, use a degreasing cleaner or dish soap with a non-scratch pad, rinse and squeegee dry. A 20-second squeegee after every shower keeps it clear.
Cloudy shower glass is one of the most frustrating things to clean. Most online advice assumes the cloudiness is hard-water scale, but Metro Vancouver's tap water is soft — it's low in the calcium and magnesium that leave thick mineral crust in other parts of Canada. In Lower Mainland bathrooms, that white film is usually soap scum: residue from soap, shampoo and body oils. That changes what works best.
Soap scum or hard water?
| Soap scum | Hard-water scale | |
|---|---|---|
| What it looks like | Dull, cloudy film; can feel slightly greasy or waxy | Hard, chalky white spots or crust |
| Where it builds | Lower half of the glass and anywhere soap splashes | Around taps, shower heads and where drops dry |
| Common in Metro Vancouver? | Yes — the usual culprit | Less common, because the water is soft |
| What removes it | Dish soap or a degreasing cleaner, a non-scratch pad, then rinse | A mild acid, like a vinegar solution, on surfaces that tolerate it |
If you're on a private well, or your building has its own water treatment, your water may be different — the test is simple: if a mild degreaser lifts the film, it was soap scum.
How to clean cloudy shower glass
- Warm the glass with a hot shower first. Warm soap scum softens and lifts more easily.
- Apply a degreasing cleaner — a few drops of dish soap in warm water works on light film. Let it sit for a few minutes.
- Scrub with a non-scratch pad, working top to bottom. Never use steel wool or abrasive powder on glass.
- Rinse thoroughly — leftover cleaner leaves its own film.
- Squeegee and dry with a microfibre cloth for a streak-free finish.
- For stubborn mineral spots around the taps, a diluted vinegar solution can help. Keep vinegar and other acids off natural stone like marble and travertine, which they can etch, and check your shower's care guide for coated glass.
How to keep it from coming back
- Squeegee after every shower. It takes 20 seconds and is the single best habit for clear glass.
- Switch from bar soap to body wash — bar soap tends to leave more residue.
- Run the exhaust fan during your shower and for a while after. A drier bathroom also means less mildew in the grout and caulking.
- Clean weekly. A quick weekly wipe beats a monthly battle.

Blue-green staining on tubs, sinks or grout usually comes from copper in older plumbing, not from dirt. Metro Vancouver raised the pH and alkalinity of its drinking water in 2021, partly to reduce copper release from pipes and the stains it causes. If staining keeps coming back, it's worth asking a plumber to take a look.
When a professional clean helps
Years of built-up film often needs more than one pass. Our standard clean scrubs the shower and tub on every visit, and a deep clean is a good reset if your bathroom hasn't had a thorough clean in a while. If your glass is etched — permanently cloudy even when clean and dry — cleaning won't fix it; that's damage to the glass surface.
Frequently asked questions
Is Vancouver water hard or soft?
Metro Vancouver's tap water is soft — low in the calcium and magnesium that cause hard-water scale. Most cloudy film on shower glass in the Lower Mainland is soap scum.
What's the best way to clean soap scum off shower glass?
Warm the glass, apply a degreasing cleaner or dish soap solution, scrub with a non-scratch pad, rinse thoroughly and squeegee dry.
Can I use vinegar on my shower?
Diluted vinegar can help with mineral spots on glass and ceramic, but keep it off natural stone like marble and travertine, which it can etch, and check the care guide for coated glass.
How do I stop soap scum from building up?
Squeegee the glass after every shower, run the exhaust fan, switch from bar soap to body wash and give the shower a quick weekly clean.
Why is my shower glass still cloudy after cleaning?
If the glass stays cloudy when it's clean and dry, it may be etched. Etching is damage to the glass surface and can't be cleaned off.
