How to Clean a Glass Shower Door — Toronto Home Guide

Glass shower doors look pristine when clean but show every water mark and soap scum deposit. The white film on glass shower doors is a combination of soap scum (fatty acids from body wash and soap) and hard water mineral deposits (calcium and magnesium). They require different treatments but both respond to acid-based cleaners.

Weekly Maintenance Clean

1. After your last shower of the day, spray the inside of the glass with undiluted white vinegar from a spray bottle
2. Let sit 5 minutes
3. Wipe down with a microfibre cloth in circular motions
4. Rinse with water and dry with a squeegee

Deep Clean — Heavy Build-Up

1. Mix equal parts white vinegar and dish soap in a spray bottle and shake to combine
2. Spray generously over the entire glass surface
3. Let sit 15–20 minutes — the vinegar dissolves mineral deposits while the dish soap cuts through soap scum
4. Scrub with a non-scratch sponge or microfibre cloth in circular motions
5. For stubborn spots, apply baking soda directly to the damp sponge and scrub — the gentle abrasion helps without scratching
6. Rinse thoroughly and dry with a squeegee, then buff with a dry microfibre cloth for a streak-free finish

Shower Door Tracks

The bottom track of sliding shower doors collects hair, soap scum, and mould:

1. Pour undiluted white vinegar into the track and let sit 10 minutes
2. Scrub with an old toothbrush
3. Rinse by pouring water through the track, then dry

Preventing Build-Up

• Squeegee the glass after every shower — it takes 30 seconds and dramatically reduces build-up between cleans
• Apply a rain-repellent product (Rain-X or similar) to clean, dry glass a few times per year — it causes water to bead and roll off rather than evaporate and leave mineral deposits
• Switch to liquid body wash instead of bar soap — bar soap creates significantly more soap scum than gel products
