A clean bathroom isn't just about appearances. Bathrooms are one of the highest-risk areas in any home for bacteria, mould and soap buildup - and without a proper routine, these problems compound quickly. This guide covers the right products, the correct order to clean in, and the details most people miss.

Start With Ventilation

Before you touch anything, open the window or turn on the exhaust fan. Cleaning products release fumes and a poorly ventilated bathroom makes the job unpleasant fast. Good ventilation during cleaning also helps surfaces dry faster, which reduces the chance of mould returning after you're done. According to NSW Health, mould grows in wet or moist areas that lack adequate ventilation.

What You'll Need

  • Bathroom spray cleaner or diluted white vinegar
  • Toilet bowl cleaner
  • Glass cleaner or white vinegar for mirrors and screens
  • At least two microfibre cloths - one for general surfaces, one for mirrors
  • An old toothbrush for grout and tight spots
  • Rubber gloves
  • A mop or floor cloth for tiles

Avoid reaching for bleach on everything by default. Bleach is effective for disinfecting toilets and treating mould but it can discolour grout, damage certain surfaces and should never be mixed with other cleaning products.

The Right Order Makes All the Difference

Cleaning in the wrong order means spreading dirt back onto surfaces you've already done. Follow this sequence every time.

1. Dust and dry wipe first

Start with the exhaust fan cover, light fittings, top of mirror frames and any shelving. Use a dry microfibre cloth before any wet cleaning.

2. Apply toilet cleaner and let it sit

Apply toilet cleaner inside the bowl and leave it while you clean everything else. Most products need at least five minutes to work properly.

3. Clean the shower

Spray cleaner over shower walls, floor and fixtures. Let it sit before wiping. Use a toothbrush for grout and tight spots.

  • Shower head - soak in vinegar
  • Grout lines - scrub thoroughly
  • Silicone seals - check for mould

4. Clean the vanity and basin

Wipe down basin, taps and benchtop. Use a toothbrush around tap bases where buildup collects.

5. Clean the toilet

Wipe the outside first, then scrub inside the bowl and flush.

6. Mop the floor last

Sweep or vacuum first, then mop. Always clean floors last.

How Often Should You Clean Your Bathroom?

For most households, a full clean once a week is ideal. Quick wipe-downs in between help maintain cleanliness.

Common Mistakes People Make

  • Using too much water
  • Cleaning in the wrong order
  • Using the same cloth everywhere
  • Skipping the exhaust fan

When Professional Cleaning Makes Sense

Some issues go beyond regular cleaning, such as deep mould, limescale or damaged grout.
