Short answer
To clean bathroom tiles, squeegee and ventilate after every shower, wash the walls and floor once a week with warm water and a pH-neutral tile cleaner, then rinse and dry. Scrub grout with a soft nylon brush, not steel wool or a green scouring pad. Keep vinegar and other acids off cement grout and natural stone, and never mix bleach with vinegar, ammonia or other cleaners. Grout that is cracked or missing, and caulk that is black inside or peeling, need repair, not more scrubbing.
Knowing how to clean bathroom tiles properly saves a lot of scrubbing. Glazed ceramic and porcelain tile is hard and stain-resistant, so the tile face is easy. The work is in the grout lines, the silicone in the corners and the shower floor, where water, soap and skin oils collect. The right routine keeps all three looking new. The wrong product can do more damage in an afternoon than years of normal use.
This guide covers the ceramic and porcelain tile found in most bathrooms: walls, tub surrounds, shower floors and the main floor. Marble, travertine and limestone need gentler care, covered briefly below and in full in our natural stone care guide. For tile floors elsewhere in the house, including winter salt at the front door, see how to care for tile and grout.
How to clean bathroom tiles: daily, weekly and deep cleaning
A clean bathroom comes from three levels of effort. The daily step takes a minute and prevents most of the problems people later try to scrub away. The weekly wash stops soap and grime building up. A deep clean every few months catches what the weekly wash misses and tells you whether the grout needs sealing.
Every day, after showers. Run a squeegee down the shower walls and glass, then leave the fan running for 20 to 30 minutes. Hang the bath mat to dry. Water that sits on grout overnight feeds pink film, mildew and white scale. Drying the surface is the most effective cleaning step there is, and it costs nothing.
Every week. Washing bathroom tiles once a week is enough for most homes. Wash the shower and tub walls, the shower floor and the bathroom floor with warm water and a pH-neutral tile cleaner. Wipe or scrub, rinse with clean water, and dry with a microfibre cloth. Rinsing matters more than most people think. Cleaner left on the tile dries into a film that dulls the glaze, attracts dirt and makes grout look darker.
Every few months. Scrub the grout properly, clean the drain and the edges of the shower floor, and check the silicone in the corners and along the tub. Then do the water test described in the deep-clean section below to see whether the grout needs resealing.
The best cleaner for bathroom tiles
The safest everyday cleaner for bathroom tiles is a pH-neutral tile and grout cleaner, mixed with warm water as the label says. Neutral cleaners lift soap, body oil and grime without attacking cement grout, stripping grout sealer or etching stone. A few drops of mild dish soap in warm water also work, as long as you rinse well, because soap leaves a film when it dries. Stronger bathroom sprays are fine on glazed tile now and then, but many are acidic or contain bleach, so look for one labelled safe for grout, and for stone if you have any in the room.
The tools matter as much as the cleaner. Use microfibre cloths and a microfibre mop, a soft nylon brush for grout lines, a narrow grout brush for corners and a white non-scratch pad for stubborn spots. Keep a squeegee by the shower. Leave steel wool and green scouring pads out of the bathroom: they scratch glazes, polished porcelain and stone, and steel wool can leave rust marks in grout.
| Cleaner or tool | Glazed ceramic and porcelain | Cement grout | Natural stone |
|---|---|---|---|
| pH-neutral tile cleaner | Yes, for routine cleaning | Yes | Use one labelled stone-safe |
| Vinegar or acidic descaler | Occasionally, rinsed off | Not for regular use | No, it etches |
| Chlorine bleach | Diluted, occasionally | Can lighten coloured grout | Avoid |
| Oxygen bleach grout cleaner | Yes | Yes, per the label | Check the label |
| Baking soda paste | Yes, gently | Yes | Test first on polished stone |
| Steel wool, green scouring pads | No | No | No |
What not to use on grout, sealed grout and natural stone
Most cleaning damage in bathrooms comes from products that are too strong for the surface. Glazed porcelain is tough, so the tile usually survives. The grout, the sealer and any natural stone take the hit.
Vinegar and acids on cement grout. Cement grout is alkaline and porous. Vinegar, lemon juice and acidic descalers slowly dissolve its surface, leaving it rougher and more open, so it stains faster. A diluted dab on a hard-water spot, rinsed off right away, is not a disaster. Using vinegar as the weekly cleaner is how grout lines turn sandy and dark over a few years.
Acids on natural stone. Marble, limestone and travertine are made of calcium carbonate, which acids eat. Vinegar, lemon and many bathroom sprays leave dull etch marks on these stones within seconds, and the marks don't clean off. Bathrooms often mix stone with porcelain, such as a marble threshold or a pebble shower floor, so check each surface before you spray. If in doubt, treat it as stone.
Harsh cleaners on sealed grout. A penetrating sealer keeps stains on the surface, but strong acids, strong degreasers and frequent bleach wear it away faster. A pH-neutral cleaner makes the sealer last. For when and how to reseal, see do you need to seal grout.
Bleach on coloured grout. Chlorine bleach can lighten grey, beige or dark grout unevenly. For mildew on coloured grout, use an oxygen bleach grout cleaner or a mildew cleaner labelled safe for coloured grout, and test it on a hidden joint first.
Abrasives, wax and "shine" products. Gritty powders, scouring pads and even melamine sponges can dull a high-gloss glaze, polished porcelain or glass mosaic over time, so test them first. Wax and oil soaps build up into a sticky film that holds dirt and makes a wet floor slippery. Tile doesn't need them.
Never mix bathroom cleaning products
This rule matters for your health as well as your tile. Bleach mixed with ammonia releases toxic chloramine gas. Bleach mixed with vinegar or any acidic cleaner releases chlorine gas. Many toilet bowl cleaners, scale removers and glass cleaners contain acids or ammonia, so mixing can happen by accident when you spray one product on a wall that still has another on it. The safe rule is simple: never mix household cleaning products.
Use one product at a time, rinse it off completely, and only then use another. Keep the fan on and a door or window open when you use anything stronger than a neutral cleaner, and wear rubber gloves for bleach, descalers and mould removers. If anyone feels dizzy, short of breath or gets irritated eyes while cleaning, leave the room and get fresh air.
Soap scum and hard water on bathroom tiles
The dull white or grey film on shower walls is usually two things. Soap scum forms when soap reacts with minerals in the water and sticks to the tile with body oils. Hard-water scale is the mineral itself, left as water evaporates, and shows up as white spots and crusty lines where water runs. Homes on well water, common in the rural areas around Ottawa, often see more of both.
Start gentle. Wet the wall with warm water, apply a soap scum remover labelled safe for grout, give it the dwell time on the label, scrub with a non-scratch pad and rinse well. A paste of baking soda and water on a damp cloth also lifts light soap scum from glazed tile.
Heavy scale may need an acidic descaler. On glazed ceramic and porcelain that is fine if you keep it off the grout as much as you can, work in small sections, don't let it dry and rinse thoroughly. Never use one on natural stone. The lasting fix is prevention: a squeegee removes water before minerals and soap dry onto the tile, and a water softener helps where the water is very hard.
Mould in corners and caulk
Black spots in shower corners, along the tub and around the shower base are mould or mildew. On grout, surface mildew usually cleans off. Use a mildew cleaner or oxygen bleach grout cleaner that is safe for your grout colour, let it sit as directed, scrub with a soft brush, rinse and dry. Then improve the airflow. A fan that vents outside and runs long enough after each shower does more than any cleaner.
Silicone caulk is different. Inside corners and the joint where tile meets the tub or shower base move slightly, so they should be filled with flexible silicone, not grout. Mould grows into silicone, not just onto it. Once the black is inside the bead, no cleaner brings it back. The fix is to cut out the old silicone completely, clean and dry the joint, and run a fresh bead of mould-resistant bathroom silicone. New silicone over old does not bond and soon peels.
Silicone that is cracked or pulling away from the tub matters even when it looks clean, because that joint keeps water out of the wall. Corner grout that keeps cracking usually means the corner was grouted when it should have been siliconed; see why grout cracks. Pink, orange and other stains have their own causes, explained in why grout turns pink, orange or black.
How to clean a tiled shower floor
The shower floor is the hardest part of a bathroom to keep clean. It is often small mosaic tile with many grout joints, it is textured for grip, soap and hair collect around the drain, and it stays wet longest.
Once a week, rinse the floor, apply a pH-neutral or grout-safe bathroom cleaner, and scrub the grout with a stiff nylon brush on a handle, working toward the drain. Rinse well, because cleaner left in the texture makes the floor slippery. Lift the drain cover or the grate of a linear shower drain and clear the hair and soap underneath. Never use oil soaps or wax on a shower floor; they fill the texture and turn a non-slip floor slippery.
Watch for water that stands in the same spot long after a shower. A tiled shower floor should slope to the drain, typically about 1/4" per foot by industry guidance, so water runs off on its own. Puddles that never drain point to a slope problem, and grout that stays dark around them is holding water. That is a construction issue, not a cleaning one. Our guide to shower pans and tiled shower floors explains how the floor is built.
How to clean floor tiles in the bathroom
Washing ceramic tile floors in a bathroom works like any tile floor, with a few bathroom habits added. Clean tile floors start dry: vacuum or dust-mop first so hair and grit aren't dragged around. Then damp-mop with warm water and a pH-neutral cleaner, using a well wrung-out microfibre mop, not a soaking one. Change the water when it looks dirty.
Give extra attention to the base of the toilet, where grout picks up stains and odours, and to the edges along the tub, vanity and walls. Clean them with a bathroom cleaner and a small brush, rinse and dry. Heated tile floors clean the same way; just don't flood them. If the floor looks cloudy after mopping, the cause is usually leftover cleaner, not dirt. Mop once with clean warm water and buff dry.
Deep cleaning grout, step by step
A deep clean every few months is how to get tile clean when the weekly wash no longer brings the grout back. If you plan to seal afterwards, pick a time when the shower can stay unused for a day.
- Ventilate and protect. Turn on the fan, open a window or door, and put on gloves.
- Pre-wet the grout with clean water, so the cleaner works on the surface instead of soaking straight in.
- Apply a grout cleaner, such as an oxygen bleach grout cleaner, and give it the dwell time on the label.
- Scrub along each joint with a stiff nylon grout brush, in small sections.
- Rinse thoroughly with clean water and wipe the tile dry.
- Let the grout dry fully, which can take a day in a damp bathroom.
Then do the water test. Put a few drops of water on clean, dry grout. If they bead up, the sealer is still working. If the grout darkens within a few minutes, cement grout is ready for a fresh coat of penetrating sealer, applied to the grout only. Epoxy grout and many high-performance grouts don't need sealing.
Steam cleaners can help on sound glazed tile and grout, but they wear sealer faster and shouldn't be aimed at silicone or cracked grout. If grout is still stained but solid after a deep clean, a grout colourant can even it out. If the stain is inside crumbling grout, the grout needs replacing.
When cleaning won't fix it
Most tired bathrooms only need a good clean and new silicone. Some problems look like dirt but are damage, and no cleaner reaches them. Stop scrubbing and have the tile looked at if you see any of these:
- Grout that is cracked, crumbling, sandy or missing from the joints
- Silicone that is black inside, peeling, or pulling away from the tub or shower base
- Tiles that are cracked, rock underfoot or sound hollow when tapped
- Grout that stays dark low on the walls or around the drain for hours after a shower
- Mould that is back within days, a musty smell, a soft spot in a shower wall, or a stain on the ceiling below
Cracked or missing grout lets water into the joints, so it should be raked out and replaced before the damage spreads; our guide to regrouting a shower explains when that works. Failed silicone is cut out and replaced. One or two cracked or loose tiles can often be replaced on their own; see how to fix chipped tile. Agora Flooring's tile and grout repair covers regrouting, replacing cracked and loose tiles, and resealing shower corners and tub edges.
Damp grout, a soft wall, returning mould and stains below usually mean water is getting behind the tile. Many older showers were tiled over drywall or green board with no waterproofing membrane, relying on grout and caulk to keep water out, which they were never designed to do. Then the lasting fix is a rebuild: the tile comes off, wet board is replaced, and a continuous membrane goes on before new tile. Our guide to waterproofing a shower explains how that works.
Renovating? Choose bathroom tile that is easier to clean
If the bathroom is due for a redo, a few choices make every future cleaning easier. Larger tiles mean fewer grout lines; our large-format tile guide covers what they need underneath. Epoxy or high-performance grout resists stains and needs little or no sealing; see epoxy vs cement grout. A mid-tone grout colour hides daily wear better than bright white.
In the shower, a niche with a sloped bottom sheds water, a linear drain allows larger floor tile, and a properly sloped, waterproofed floor dries quickly. Glossy wall tile wipes clean but shows water spots, while textured floor tile is safer underfoot but needs a brush. Our guide to choosing shower tile weighs these trade-offs, and the bathroom renovation guide shows how a full remodel comes together. Agora Flooring handles the tile, shower waterproofing and heated floors in a renovation; plumbing, electrical and glass are done by those trades.

Frequently asked questions
How do you clean bathroom tiles?
Squeegee the shower and run the fan after every use, then wash the tile once a week with warm water and a pH-neutral tile cleaner. Scrub the grout with a soft nylon brush, rinse with clean water and dry. Every few months, deep-clean the grout and check whether it needs resealing.
What is the best cleaner for bathroom tiles?
For routine cleaning, a pH-neutral tile and grout cleaner is the safest choice for glazed tile, cement grout and grout sealer. Use an oxygen bleach grout cleaner for deep cleaning, and a stone-safe cleaner on any marble, travertine or limestone.
Can you clean bathroom tiles with vinegar?
Glazed ceramic and porcelain can handle occasional diluted vinegar on a hard-water spot if you rinse it off. Don't use it as a regular cleaner, because acids slowly wear cement grout, and never use it on natural stone, which it etches. Never mix vinegar with bleach.
How do you get tile clean when the grout is black?
Pre-wet the grout, apply an oxygen bleach or mildew cleaner that is safe for your grout colour, scrub with a stiff nylon brush and rinse. If the black is in the silicone in the corners, it has to be cut out and replaced. Mould that returns within days usually means moisture is getting into the grout or behind the tile.
How do you wash ceramic tile floors without leaving a film?
Vacuum first, then damp-mop with warm water and a pH-neutral cleaner using a microfibre mop. Use only as much cleaner as the label says, change the water when it gets dirty, and finish with a clean-water pass if needed. A cloudy floor after mopping is usually leftover cleaner or soap.
How often should bathroom tiles be cleaned?
Dry the shower after every use, wash the walls and floor once a week, and give the grout a deep clean every few months. Busy family bathrooms may need the weekly wash more often.
