How to Clean a Glass Shower Door

Glass shower doors collect soap scum, hard water deposits, and mildew faster than almost any other surface in your home. The good news: you don't need commercial cleaners or elbow grease that leaves you exhausted. The real trick is understanding what you're actually cleaning—hard water minerals bond differently than soap residue, and mildew needs a different approach than either. Get this right, and your door stays clear for weeks between cleanings. Rush it, and you're back in there in three days fighting streaks.

1. Prepare the bathroom and gather your tools. Open a window or turn on the exhaust fan to get air moving. Lay out your squeegee, microfiber cloth, spray bottle, and vinegar near the shower. If you're dealing with heavy buildup, fill a small bucket with warm water and set it aside. This takes two minutes and makes the actual cleaning seamless.
2. Mix and apply your cleaning solution. Fill a spray bottle with equal parts white vinegar and water—no need to measure precisely, just eyeball it 50-50. Spray the entire glass door generously, starting at the top and working down. Don't skip the frame, tracks, or the bottom edge where soap pools. Spray until the glass looks wet, not dripping.
3. Let the solution dwell on tough stains. Walk away for 15 minutes. The vinegar needs time to dissolve mineral deposits and loosen soap scum. If you see the solution drying, spray again. For glass that hasn't been cleaned in months, let it sit 20–30 minutes or even apply the solution twice.
4. Scrub only where needed. Spray the solution fresh one more time. Use a non-abrasive sponge or soft brush to gently scrub areas with visible buildup—corners, the frame, and heavy soap scum spots. The vinegar has already done the chemical work; you're just physically removing what's loosened. Don't scrub the entire door; most of it will wipe clean.
5. Squeegee the door dry. Starting at the top of the glass, pull the squeegee down in one smooth stroke, wiping the blade on a towel between each pass. Overlap each stroke slightly. Work methodically side to side until you've covered the entire door. Squeegee the frame last to catch any runoff.
6. Final wipe with microfiber cloth. Use a dry microfiber cloth to catch any remaining streaks or droplets. Wipe in vertical strokes, not circular, to avoid leaving lint. Pay special attention to the edges and seals where water pools. This step takes 90 seconds and makes the difference between clean-looking and actually clean.
7. Address hard water stains if needed. If vinegar alone doesn't remove white, cloudy deposits, make a paste of baking soda and vinegar (roughly 3 parts baking soda to 1 part vinegar). Apply it directly to the stains and let it sit for 10 minutes. Scrub gently with a soft brush, then rinse and squeegee dry. For stubborn mineral buildup, repeat.
8. Maintain the door between cleanings. After each shower, do a quick squeegee pass on the door. This removes standing water and prevents mineral deposits from forming. Once a week, spray with vinegar solution and wipe. This routine keeps heavy cleaning sessions to once a month instead of weekly.
