> [!tip] Quick answer: Top-down, dry-then-wet. Dust ceiling fans and vents, wipe down walls and mirrors, scrub the shower and tub, clean the toilet, wipe counters and sinks, then mop the floor last. Allow 60 to 90 minutes for an average bathroom. ## How to deep clean a bathroom in 2026 A monthly deep clean keeps a bathroom looking and smelling new, and prevents the buildup that turns weekly maintenance into an hour-long job. The right order matters: top to bottom, dry to wet. Cleaning the floor first means you'll re-dirty it when you scrub the shower; cleaning wet surfaces before dry ones spreads dust into mildew. This guide covers a typical full bathroom (toilet, shower or tub, sink, vanity, floor). For half baths, skip the shower steps. ### What you should plan for - Time: 60 to 90 minutes - Tools: Vacuum, microfibre cloths, scrub brush, mop, dedicated bathroom cleaners - Cost: Under $30 for a full kit - Frequency: Monthly for full deep clean; daily and weekly maintenance in between - Critical: Open windows and run the exhaust fan throughout ## The 10-step deep clean (in order) 1. Ventilate. Open the window and run the exhaust fan from start to finish. 1. Pre-treat the shower and toilet. Spray vinegar in the shower, drop a toilet cleaner tablet in the bowl. Let both sit while you work on everything else. 1. Dust top-down. Ceiling fan, vent covers, light fixtures, tops of cabinets and door frames. 1. Wipe walls and switches. Damp microfibre. Pay special attention to areas above the toilet and around the door handle. 1. Clean mirrors and windows. 50/50 vinegar-water spray, dry with newspaper or a clean microfibre for streak-free shine. 1. Scrub the shower or tub. See how to clean shower tiles and how to clean shower mould for detail. 1. Clean the toilet. Inside the bowl (the cleaner has been working), under the rim, seat top and bottom, base. Don't forget the floor right behind it. 1. Wipe counters, sinks, and faucets. Mild bathroom cleaner and microfibre. Use a toothbrush for faucet bases and around drains. 1. Empty and clean the trash bin. Wipe inside and out; replace the bag. 1. Mop the floor last. Top-to-bottom dirt has fallen here. Sweep or vacuum first, then mop with a vinegar-water solution. ## What you'll need ## The order matters: why top-down, dry-then-wet Dust falls. If you clean the floor first, dust from the ceiling fan and vents lands on it. If you mop before scrubbing the shower, you'll splash soap and water onto a clean floor. Wet surfaces hold dust. If you spray cleaner on a dusty mirror, you create a streaky paste. Always dust first, wet-clean second. ## Common mistakes 1. Skipping ventilation. Cleaning fumes plus humidity equals lingering smells and faster mould regrowth. Open the window and run the fan throughout. 1. Mixing cleaners. Bleach + ammonia (in some bathroom cleaners) creates toxic chloramine gas. Use one cleaner at a time and rinse fully between. 1. Cleaning bottom-up. Spreads dirt onto clean surfaces. Always top-down. 1. Forgetting the trash bin. The bin itself collects splatter and odour. Empty and wipe monthly. 1. Reusing the same cloth everywhere. Use different microfibres for toilet, counters, and mirrors. Cross-contamination is real. ## Weekly maintenance to keep deep cleans easy Between monthly deep cleans: - Squeegee the shower after every use - Wipe counters and sink after morning use (60 seconds) - Quick toilet brush + bowl cleaner weekly - Sweep or vacuum the floor weekly - Empty the trash bin weekly These habits make the monthly deep clean a 60-minute job instead of a 2-hour deep purge. ## Stubborn problems ### Soap scum Vinegar spray + baking soda paste. Let sit 15 minutes, scrub with a soft brush. ### Hard-water stains on faucets Wrap faucets in vinegar-soaked paper towels for 30 minutes; scrub with a toothbrush. ### Toilet ring (calcium) Pour 1 cup of vinegar into the bowl, let sit 1 hour, scrub with a pumice stone made for toilets. ### Grout discolouration See how to clean grout for the full method. ### Mildew on caulking See how to clean shower mould. If mould has penetrated caulking, replace it. ## FAQs about deep cleaning a bathroom How long does a full bathroom deep clean take? What's the best order to clean a bathroom?
