Key Takeaways
- Clean bathroom tiles from the top down, and do the floor last. NEA’s own home cleaning guidance says to clean from high to low, wall to floor.
- Most grey grout is soap scum, body oil and dirt, not damage. A baking soda paste and a stiff brush lift most of it.
- Keep toilet bowl cleaner in the toilet bowl. Strong acids wear down cement grout, which then stains faster.
- Never mix bleach with vinegar, ammonia or toilet bowl cleaner. The combinations release toxic gas.
- Bathroom Deep Cleaning from Urban Company Singapore starts from S$65, using high-temperature steam disinfection and heavy-duty scrubbing tools.
It’s Sunday morning in a 4-room flat in Sengkang. The grout lines have gone from white to dull grey, and there’s a brown film by the floor trap that mopping won’t shift. Most of it comes off with kitchen-cupboard basics, used in the right order.
Why Do Bathroom Tiles and Grout Get So Dirty?
Bathroom tiles get dirty because soap, body oil and minerals in tap water dry onto them after every shower, and grout soaks that film up. Grout is cement-based and porous, so it holds what smooth glazed tiles shed.
Singapore adds 2 problems. Most HDB bathrooms are fully wet, so the whole floor gets soaked. And in the humidity, a bathroom without a window or exhaust fan stays damp for hours, and damp grout picks up dirt faster.
| What you see | What it usually is | What shifts it |
|---|---|---|
| Dull, filmy wall tiles | Soap scum | Detergent, then diluted vinegar on glazed tiles |
| Grey or brown grout | Soap scum, oil and dirt | Baking soda paste and a stiff brush |
| Dark film by the floor trap | Dirt where water pools | Detergent and a deck brush |
| Orange rings on the floor | Rust from cans left on wet tiles | Diluted vinegar, rinsed off |
| Black spots in silicone that return within days | Mould inside the silicone | Usually new silicone, not more scrubbing |
How Do You Clean Bathroom Tiles Step by Step?
Clean bathroom tiles in 4 steps: ventilate, wash the walls, scrub the grout, then do the floor. Budget about an hour if the grout hasn’t been done in a while.
- Ventilate first. Open the window or run the exhaust fan. NEA’s guidance on cleaning and disinfecting residences recommends fresh air during and after cleaning, and cleaning from high to low.
- Wash the wall tiles. Wipe with warm water and a few drops of dishwashing liquid. For filmy soap scum on glazed tiles, spray a 1:1 mix of white vinegar and water, leave it 5 to 10 minutes, then rinse.
- Scrub the grout. Mix baking soda and a little water into a thick paste, the same trick that lifts baked-on grease inside an oven. Spread it on the grout, wait 10 to 15 minutes, then scrub along each line with a stiff brush.
- Finish with the floor. Scrub with detergent and a deck brush towards the floor trap, rinse, squeegee, and dry the corners.
Shower head and toilet bowl stains are limescale and need a different method, as do glass shower screens and mirrors, so they’re left out here.
How Do You Clean Toilet Floor Tiles and the Floor Trap?
Toilet floor tiles need a deck brush, not a mop, because most HDB bathrooms use textured anti-slip tiles that trap dirt in their grooves. A mop glides over the top and leaves it there.
Don’t miss 3 spots: behind the toilet bowl, the base of the walls, and the ring around the floor trap. Lift the trap cover, rinse out hair and soap, and scrub the grating. NEA’s dengue advice is also to cover rarely used gully traps and fit anti-mosquito valves, especially in a second bathroom nobody uses.
If water pools because the trap drains slowly, that’s a choke, not dirt. Treat it like a choked toilet bowl: try the simple fix first, then call a plumber.
Which Products Are Safe on Bathroom Tiles and Grout?
Mild detergent, baking soda and diluted white vinegar are safe for routine cleaning of glazed ceramic and porcelain tiles. Trouble starts with stronger products, and with mixing them.
| Product | Good for | Avoid on | Never mix with |
|---|---|---|---|
| Baking soda paste | Grout, floor stains | Nothing, if rinsed | Vinegar in the same step |
| Diluted white vinegar | Soap scum on glazed tiles | Marble, natural stone; grout every week | Bleach |
| Oxygen bleach | Grout still grey after scrubbing | Coloured grout (test first) | Other cleaners |
| Chlorine bleach | Occasional disinfecting, well diluted | Daily use; coloured grout | Vinegar, ammonia, toilet bowl cleaner |
| Toilet bowl cleaner | Inside the toilet bowl | Tiles and grout | Bleach |
Never mix bleach with vinegar, ammonia or toilet bowl cleaner. Bleach and acids release chlorine gas; bleach and ammonia release chloramine gas. NEA’s list of disinfection products tells households not to mix different disinfectant products and to use them in a well-ventilated area. Rinse with plain water before switching products, and wear rubber gloves for anything stronger than detergent.
How Do You Stop Grout Getting Dirty Again?
Keep it dry. Squeegee the walls and floor after the last shower of the day, leave the fan on or window open for 30 minutes, and don’t leave bottles or cans standing on the floor. A weekly tile wipe-down and a monthly grout scrub suit most homes. For what a routine clean covers versus a once-off one, see how deep cleaning differs from regular cleaning.
When Is It Worth Getting a Professional?
It’s worth getting help when the grout stays dark after 2 or 3 proper scrubs, when you’re moving in or out, or when nobody has the hours. Routine tile cleaning and a monthly grout scrub are fair DIY jobs.
Bathroom Deep Cleaning from Urban Company Singapore starts from S$65. The method is “high-temperature steam disinfection for a germ-free clean”, with “deep scrubbing with heavy-duty tools to remove stains and buildup”. If you’re weighing that against your own weekend, here’s whether hiring a cleaning company is worth it.
One boundary: cracked or missing grout can’t be cleaned back. It lets water into the floor and walls, so it needs regrouting. Replacing bathroom tiles in an HDB flat falls under HDB’s renovation rules, so check them before booking anyone.

Frequently Asked Questions
What is the best way to clean bathroom tiles?
Work from the top down. Rinse the walls with warm water, wipe them with a mild detergent, then use diluted white vinegar on any filmy soap scum on glazed tiles. Scrub the grout lines with a baking soda paste and a stiff brush, rinse everything, and squeegee or dry the floor last.
How do you clean grout on floor tiles?
Spread a paste of baking soda and a little water along the grout lines, leave it for 10 to 15 minutes, then scrub along each line with a stiff grout brush or old toothbrush. Rinse well. For grout that stays grey, an oxygen bleach solution left for the time on its label usually lifts it.
Can you use toilet bowl cleaner on bathroom tiles?
It is better not to. Many toilet bowl cleaners are strongly acidic and made for glazed porcelain only. On cement grout they can wear the surface away and make it stain faster, and some contain bleach. Keep toilet bowl cleaner inside the bowl, and use a mild detergent or baking soda on tiles and grout.
Is vinegar safe for bathroom tiles?
Diluted white vinegar is fine on glazed ceramic and porcelain tiles for soap scum and water marks, if you rinse it off afterwards. Avoid it on marble, limestone and other natural stone, which acid can etch, and do not use it on grout every week. Never mix vinegar with bleach.
How often should you clean bathroom tiles in Singapore?
A quick wipe and squeegee after showers, a proper clean of tiles and floor once a week, and a grout scrub about once a month suits most HDB bathrooms. Singapore humidity keeps grout damp for longer, so a bathroom that stays wet between showers usually needs the grout done more often.
When should you get a professional bathroom deep clean?
When the grout has stayed dark after 2 or 3 proper scrubs, before moving in or out, or when nobody at home has the time. Urban Company’s Bathroom Deep Cleaning uses high-temperature steam disinfection and heavy-duty scrubbing tools. Cracked or missing grout is a repair job, not a cleaning one.
