How to Clean a Bathroom Properly — Not Just Make It Look Clean

The bathroom is the room most people feel most confident about cleaning. It gets done regularly. There's a clear routine. But after cleaning hundreds of bathrooms professionally across Adelaide, I can tell you that most DIY bathroom cleans — even the thorough-feeling ones — consistently miss the same spots, use the wrong sequence, and achieve a result that looks clean without actually being hygienic.

This guide is the professional method. The sequence matters. The products matter. And the spots most people skip matter more than you'd think.

Why Sequence Matters More Than Product Choice

Before we get into the steps, understand this: the order you clean a bathroom in determines whether you're cleaning it once or cleaning it twice.

The most common mistake is cleaning the floor first, or cleaning the toilet last and then walking across a floor you've just mopped. Or spraying product, wiping immediately, and moving on — instead of letting it dwell.

The professional sequence is always top to bottom, dry before wet, dwell time first. Spray your products, do your dry work while they soak, then come back and wipe.

What You'll Need

• Microfibre cloths (minimum 3 — one for toilet, one for sink/basin, one for mirror/glass)
• Toilet brush
• Bathroom disinfectant spray
• Glass cleaner or diluted white vinegar for mirrors
• Tile and grout cleaner or a diluted bleach solution for grout
• Mould spray if needed
• Scrubbing brush or old toothbrush for grout and tight corners
• Mop and bucket, or a flat mop for the floor
• Rubber gloves

Do not use the same cloth on the toilet that you use on the basin. This is how cross-contamination happens.

Step 1: Ventilate and Spray First

Open the window or turn on the exhaust fan. You'll be using cleaning products that need airflow.

Then spray everything before you touch anything:

• Spray the inside of the toilet bowl with toilet cleaner or bleach solution
• Spray the toilet seat, lid, outer bowl and base with disinfectant
• Spray the shower walls, screen and floor with your bathroom cleaner
• Spray the basin, taps and surrounding surfaces
• Spray the floor if it's tiled

Now leave all of that to dwell for at least 3–5 minutes while you do your dry tasks. Dwell time is what separates a proper clean from a surface wipe.

Step 2: Dry Tasks While Products Dwell

While your sprays are sitting:

Dust and wipe down: Use a dry microfibre cloth to wipe down the top of the mirror frame, light fittings, exhaust fan cover, tops of door frames, and any shelving. Dust falls downward — do this before any wet work.

Remove everything from surfaces: Soap dispensers, shampoo bottles, toothbrush holders. Put them somewhere outside the bathroom or on the toilet lid. You need to clean under and around them, not just around them.

Check the exhaust fan cover: If it's clogged with dust, it's not working properly. Wipe it with a dry cloth or use a vacuum brush attachment.

Step 3: Clean the Toilet — Properly

The toilet gets cleaned in a specific order to avoid spreading contamination.

1. Scrub the bowl first — Use the toilet brush to scrub under the rim, around the waterline and at the bottom. The product has been dwelling for several minutes now and will lift staining and kill bacteria effectively. Flush to rinse.

2. Wipe the flush button or handle — This is one of the most touched surfaces in the house and one of the most skipped. Use your dedicated toilet cloth with disinfectant and wipe thoroughly.

3. Wipe the seat, lid (both sides), and outer bowl — Work from the cleaner areas to the dirtier ones. Lid first, then seat top, then seat underside, then outer bowl.

4. Clean the base and behind the toilet — Get down and look behind the toilet. The floor area at the base collects urine splatter, dust and grime and is almost universally skipped in DIY cleans. Use disinfectant and your cloth or a scrubbing brush.

5. Wipe the cistern — The cistern top and sides accumulate dust and grime. Wipe it down with disinfectant.

Bag or fold your toilet cloth so it doesn't touch anything else. Do not use it on the basin.

Step 4: Clean the Shower and Bath

By now your shower spray has dwelled long enough to be effective.

Glass shower screen: Use a squeegee or microfibre cloth to wipe the screen from top to bottom. For hard water staining or calcium buildup on glass, a dedicated calcium remover is needed — general bathroom spray will not cut through mineral deposits. In Adelaide specifically, hard water staining is a constant issue due to our high mineral content water — for the complete removal method, see our guide to removing hard water stains from shower glass.

Shower walls: Wipe tiles from top to bottom. Pay attention to the grout lines — a scrubbing brush or grout brush makes a significant difference. If there's mould in the grout, a dedicated mould spray applied and left for 10 minutes before scrubbing is more effective than standard bathroom cleaner.

Shower floor and drain: The drain is often the source of bad bathroom smells. Remove the drain cover, clear any hair and debris, and pour a small amount of disinfectant down before replacing the cover. Scrub the shower floor — particularly the corners where soap scum accumulates.

Shower head: Check for limescale buildup around the nozzles. A plastic bag filled with white vinegar, secured around the shower head overnight, dissolves calcium deposits effectively.

Bath (if applicable): Scrub the basin, then the sides, then around the taps. Pay attention to the silicone sealant around the bath edge — this is a common mould site.

Step 5: Clean the Basin, Taps and Vanity

Work from the cleanest to the dirtiest:

1. Mirror first — Spray glass cleaner or diluted vinegar and wipe with a clean dry microfibre cloth. Use horizontal strokes, not circular, to avoid streaking. Check from an angle to catch any spots.

2. Vanity top and shelving — Wipe down the entire surface, including areas that were under bottles and dispensers. Put items back one at a time, wiping the base of each.

3. Basin — Scrub the basin interior, paying attention to the waterline where toothpaste and soap scum accumulate. Use an old toothbrush around the drain and the overflow hole — these areas are impossible to clean with a cloth.

4. Taps — Wipe the entire tap including the base where it meets the basin. This junction collects calcium, soap and grime. A toothbrush is useful here too. In Adelaide's hard water environment, a vinegar-soaked cloth held against taps for a few minutes will dissolve calcium buildup.

5. Tap handles and any other fixtures — Disinfect these. They're high-touch surfaces.

Step 6: Walls, Light Switch, Door Handle

Wipe down the lower wall tiles if they need it. Then — and this is consistently skipped — disinfect the light switch and door handle. Every person who uses the bathroom touches these surfaces. They need to be disinfected at least weekly.

---

Step 7: Floor Last

The floor is always last. By now everything above it has been cleaned and any drips or spray overspray has landed on the floor.

Sweep or vacuum first to remove hair and loose debris — mopping over hair just pushes it around. Then mop with a floor cleaner suitable for your tile type, starting from the furthest point from the door and working toward the exit. Do not walk back across a wet floor.

Pay attention to:

• Corners and edges where a mop head doesn't reach well (a cloth or scrubbing brush finishes these)
• The area directly in front of the toilet
• Behind the door

The Three Spots Most DIY Cleans Miss

After years of doing this professionally, these are the three most consistently overlooked areas:

1. Behind and at the base of the toilet — The floor area immediately surrounding and behind the toilet base. Urine splatter, dust and grime accumulate here and it's a genuine hygiene issue.

2. The overflow hole in the basin — That small hole near the top of the basin exists to prevent overflow. It accumulates biofilm, mould and grime and is almost never cleaned. An old toothbrush and disinfectant sorts it.

3. The underside of the toilet seat — People clean the top of the seat. The underside accumulates splash, grime and bacteria and is consistently missed.

How Often Should You Deep Clean Your Bathroom?

A surface wipe of the basin and toilet should happen every few days. A full clean using the sequence above should happen weekly. A deeper clean — including scrubbing grout, descaling shower glass and cleaning drainage — should happen monthly.

If you have a professional cleaner, make sure they're following a genuine sequence and not just doing a surface wipe that looks clean. The test is simple: check behind the toilet, check the drain, check the overflow hole in the basin.

Final Thought

A bathroom that looks clean and a bathroom that is genuinely hygienic are not the same thing. The difference is sequence, dwell time, the right products for the right surfaces, and attention to the spots that don't show up in photos but matter most for your family's health.
