Bathroom Brilliance: Professional Techniques for End of Tenancy Cleaning

60% of deposit disputes in the UK happen because of cleaning issues, with insufficient bathroom cleaning being a top reason. Unfortunately, 70% of tenants underestimate cleaning expectations at checkout. Prone to moisture, mould, and hard water that causes limescale buildup, UK bathrooms are a challenge for inexperienced tenants. Grout lines and areas behind toilets make bathroom cleaning even more challenging. A dirty bathroom will lead to unpleasant deposit deductions, even if the rest of the property is clean. Using professional techniques will help you avoid deductions. Our guide covers everything you should do to leave the bathroom immaculate, as professional cleaners would do. As for the attention to minute detail and elbow grease—that's entirely up to you!

What landlords mean by “clean”

Under the UK’s Tenant Fees Act 2019 and Deposit Protection Schemes, tenants should return the property in a condition similar to move-in, considering fair wear and tear. This is known as “reasonable cleanliness”. Landlords can’t expect spotless but a hygienic, professionally clean look. End-of-tenancy inspections are compared against the check-in inventory, and if the bathroom doesn’t meet the same standards, deposit deductions will come.

During final inspections, landlords examine hotspots like mouldy grout or silicone, limescale-covered taps and showerheads, water-stained mirrors, and unsanitised toilets. Behind and under the toilet, inside cabinets, and extractor fans are thoroughly examined by landlords—they should be immaculate.

Mind that hard water is an essential provocation across much of the UK, and it leaves behind difficult limescale on taps, showerheads, tiles, and glass. If unaddressed, the mineral buildup looks unsightly and causes deposit deductions. Regular cleaning isn’t enough, and deep descaling is paramount.

Professional vs. DIY--Why a deep clean is more than just regular cleaning

While a DIY cleaning may cover the basics, the professionals will focus on typically overlooked areas that make an impressive difference. Professionals come with industrial-grade tools (grout brushes and industrial-grade cleaners) to handle difficult grime, mould, and limescale that are tricky to remove with off-the-shelf products.

Attention to detail is another aspect that distinguishes professional cleaning from regular cleaning. The pros carry the expertise to detect any hidden dirt cleaning around toilet bases, in extractor fans, or within grout lines—areas that most tenants miss. Professionals follow a field-proven process and clean all nooks and crannies in the bathroom. The extra effort and expertise of professional cleaners result in a spotless bathroom that helps to secure it.

Gear up like a pro

Essential equipment

Having the right tools is essential to get professional-grade results. Here’s what you need:

Brushes

• Grout brushes—to scrub grout lines and remove dirt, mould, and mildew
• Scrub brushes—when cleaning around the toilet base or under taps
• Detail brushes for intricate spots

grout tools

these tools are for deep cleaning and restoring grout.

Cloths

Choose microfiber cloths as they trap dust and dirt and leave surfaces streak-free. You can use them for drying and buffing polished surfaces like chrome fixtures and mirrors.

Gloves

Protect your hands from grime and harsh chemicals, and use heavy-duty gloves for complex cleaning tasks.

Eco-friendly vs. commercial-grade cleaners

Eco-friendly cleaners

Made from natural, biodegradable ingredients gentle on the environment and your health, eco-friendly cleaners don’t contain harsh chemicals and are safe for tenants and pets. They’re helpful for daily upkeep, but some require enhanced elbow grease for difficult stains.

Commercial-grade cleaners

These cleaners use more potent chemicals to remove difficult stains, limescale, and heavy-duty grime. They ensure faster, more powerful results and are efficient for difficult deposits, tough limescale, and embedded grime. If mishandled, the harsh chemical may damage sensitive surfaces, generate strong fumes, or pose health risks.

How to choose?

For routine maintenance and light stains, go with eco-friendly cleaners. If you must remove mould, limescale, or old stains, choose commercial-grade products—but carefully use them!

Avoid damage

Some cleaners may damage surfaces like tiles, stones, and chrome and cause corrosion, discolouration, or surface degradation. Here’s what to avoid when cleaning the bathroom:

 Acidic cleaners

You may find them in some bleach products, limescale removers, and rust removers. They erode natural stone surfaces (marble, granite) or strip the protective finish from chrome, causing pitting, dullness, or discolouration.

Solution: Use pH-neutral cleaners or gentle descalers for natural stone or chrome.

Abrasive cleaners

Gritty (cream cleansers) or powder-based cleaners are abrasive and can scratch delicate surfaces, including tile and polished chrome, causing marks and removing gloss.

Solution: use non-abrasive, soft cloths or sponges.

Bleach-based products

Strong bathroom cleaners or disinfectants are made with bleach. Even though it’s effective against mildew and mould, bleach causes fading and discolouration on tiles and grime. If left for too long, it will tarnish chrome fixtures.

Solution: sparingly use bleach and always rinse thoroughly. Switch to hydrogen peroxide or eco-friendly mould removers.

Ammonia-based cleaners

Some glass or window cleaners contain ammonia, which can be harsh on granite or marble. It makes them degrade or lose their shine.

Solution: First, use ammonia-free cleaners or test products on small, hidden areas.

Oily or greasy cleaners

Furniture polish or oil-based cleaners are typically oily. They can leave residues that attract dirt, so it’s more challenging to maintain surfaces, especially tile and chrome.

Solution: stick to cleaners made for bathrooms as they are residue-free and don’t leave a film on surfaces.

Tips to avoid damage:

• Always test cleaners on a small, hidden area before applying them to the whole surface
• Use sponges, soft cloths, or microfiber towels to avoid scratching
• Carefully read labels to ensure products are safe for your materials in the bathroom.

Don’t forget about your safety.

Protective gear

Always wear rubber or nitrile gloves and a dust mask or respirator when using strong cleaners or removing mould, mildew, or dust to protect your skin from detergents and harsh chemicals. When cleaning around taps or toilets, shield your eyes from splashes or irritants with goggles.

Ventilation

Open windows and doors and use fans in confined spaces to improve air circulation. If you tackle mould or mildew, use a dehumidifier to control moisture levels and prevent the spores from spreading.

Chemical handling

Store chemicals clearly labelled in a cool, dry place, out of reach of children and pets. Never mix some cleaners, like bleach and ammonia, as some combinations generate harmful gases.

Surface protection

place drop cloths or protective sheets under equipment and furniture to protect the flooring and surfaces from possible spills. Opt for eco-friendly, non-toxic cleaners whenever possible to minimise the risk of allergic reactions and chemical burns.

Prepare for emergency

have a basic first aid kit (with bandages, antiseptic wipes, and eye wash solution) and learn emergency contact numbers for poison control or medical assistance.

Step-by-Step: The Professional Bathroom Deep Clean

Prep & Planning

There’s a long way until scrubbing begins:

Declutter

Remove all your belongings to clear the way for cleaning and protect them. Wipe down shelves or storage areas to remove dust and grime.

Detect the problematic spots.

Check out the high-traffic zones (around the toilet, sink, or shower) and focus on hidden areas like under the sink, the grout between tiles, or behind the toilet. Jot down areas needing extra care, pre-treatment or specific products.

Pre-treatment

For efficient cleaning, pre-treat difficult stains and buildup and apply cleaning products (vinegar solution, limescale remover) to stubborn grime or hard water stains. Allow the products to work for 10-15 minutes to break down the soap scum, limescale, or general buildup. Use a grout cleaner/descaler for heavily soiled surfaces.

Shower & bath blitz

Limescale removal

Use a limescale remover or a white vinegar solution to dissolve the mineral deposits around taps, tiles, and shower screens. After allowing it to work for 10-15 minutes, scrub with a non-abrasive brush or sponge and polish the taps with a microfiber cloth for a sparkly finish.

Showerhead descale

Remove the showerhead and soak it in a solution of vinegar and water (30-60 minutes). Use a toothbrush to scrub the nozzle and remove hard-to-reach deposits. Place the showerhead back in after cleaning it.

Grout & mould

Use a specialised grout cleaner or a bleach solution to scrub the grout and remove difficult stains. Apply mould removal sprays and scrub after several minutes. To stop future growth, apply a mould-resistant grout sealer and limit moisture buildup by drying all surfaces.

Curtain & screen refresh

Soap scum, grime, and mould can accumulate on shower curtains, whereas difficult streaks will appear on shower screens. You can wash shower curtains in the machine with detergent or gently scrub them with a mild cleaner if the fabric is delicate. Remove water spots and streaks from the shower screens with a glass cleaner or a vinegar solution.

Sink & vanity

Tap & drain

Remove mineral deposits from taps and drains with a vinegar solution. After allowing it to work for a few minutes, scrub it with a soft brush or a microfiber cloth. Buff out streaks and watermarks with a polishing cloth. Use a plumber’s snake, baking soda, and vinegar solution to clean drains and remove debris.

Streak-free mirrors

Spray a glass cleaner or a DIY solution (1:1 ratio of water and vinegar) to remove water spots, soap residue, and toothpaste splatters. Wipe with a microfiber cloth in a circular motion and buff to shine with a clean cloth. Break down difficult spots with a specialised mirror cleaner.

Cabinet interior cleaning

Empty the cabinet's contents and use a damp cloth to wipe down shelves and a small brush or vacuum cleaner attachment for hard-to-reach spots. Use a baking soda paste or a mild cleaner for stains or sticky spots. Wipe down the door handle and exterior and ensure everything is dry before returning your things.

Countertop cleaning

Various materials are used to clean countertops, and you need to use the adequate cleaning technique for each:

• Granite or marble—use a pH-balanced cleaner and avoid abrasive cleaners. Prevent streaking by wiping it down with a microfiber cloth.
• Laminate—it withstands strong cleaners, and you can use a multisurface cleaner and gently scrub with a soft cloth to not scratch it.
• Wood—use a wood-friendly cleaner and avoid excessive moisture. Finish with a polish formulated for wood surfaces to reveal the natural sheen.
• Quartz—use a mild cleanser and a microfiber cloth for a streak-free shine. Be careful not to scratch the surface.

Toilet

Pro sanitising

For thorough sanitising, use a strong disinfectant specially made for toilet bowls. Cover all areas, including the rim, and allow it to work for a few minutes. You can also disinfect the seat, lid, and flush handle. Scrub away grime and stains in the bowl with a toilet brush and wipe all surfaces with a disinfectant wipe or cloth for best results.

Hard water ring removal

Use a limescale remover or a vinegar and baking soda solution to remove hard water rings. Pour vinegar into the bowl and add baking soda—let them work for half an hour. Lift the deposits by scrubbing them with a toilet brush or pumice stone. Be gentle, especially when cleaning ceramic surfaces. Flush to rinse the toilet clean.

Under & behind: hidden spots that matter

Grime, dust, and bacteria can be collected behind the toilet and under the rim. Use a small brush or microfiber cloth to clean these spots. If possible, tilt the unit to clean behind the toilet and disinfect hidden spots. Wipe the pipes and the base of the toilet too.

Deodorising techniques

Deodorise the toilet with an odour-neutralising spray or baking soda and place it in the bowl. Use toilet deodoriser tablets in the tank or air fresheners in the bathroom for ongoing freshness. Apply essential oils to a cotton ball and place it in the toilet tank. The oils will disperse while flushing, leaving the bathroom nice smelling.

Floors & tile

Grout detail work

Use a specialised grout cleaner or make your paste (baking soda and water) and apply it right on the grout lines. Let it sit for 10-15 minutes, and lift the stains afterwards with a grout cleaning tool or stiff-bristled brush. If the areas are filthy, use a pumice stone or a steam cleaner without damaging the grout and wipe with a damp cloth for the finish.

Tile/vinyl deep cleaning

Use a multi-surface cleaner or a solution of vinegar and water for tiles. Choose a vinyl-safe cleaner or a mild, soapy solution to clean vinyl floors. Apply cleaners to the whole surface and focus on dirt and stains. Use a soft-bristled brush of microfiber cloth to scrub the tiles and a damp cloth to clean the surface. Steam cleaning is also an option, especially if the tiles have grout lines that collect dirt.

Corners & edges

Use a small detailing brush or an old toothbrush to clean hard-to-reach areas and focus on baseboards. Wipe them down with a mild cleaner and a damp cloth. Look for signs of buildup at the edges and clean without damaging the finish.

Dry & polish

Follow up with a tile shine product or floor polish, especially if you have vinyl or ceramic tiles. Don’t use products that make vinyl floors slippery, but a dry polishing cloth or mop. As for ceramic tiles, you may use a polishing agent to seal the tiles and grout.

Troubleshooting the tough stuff

Mould, limescale, rust, and drain odours require a special approach and know-how.

Mould & mildew: removal + prevention

Removal

Apply a mould and mildew remover with hydrogen peroxide or bleach to the affected area. Allow it to sit for 10-15 minutes, and use a brush or sponge to scrub it away. For grout lines, apply a mixture of baking soda and water.

Prevention

Dry the surfaces with a microfiber cloth and create a barrier against moisture with a silicone-based sealant. Ensure efficient ventilation or install a dehumidifier to keep the bathroom dry and prevent future mould growth.

Severe limescale

If standard cleaners aren’t efficient, use a commercial descaling product or mix equal parts white vinegar and water. Apply to areas affected by limescale and let it sit for 15-30 minutes. Use a soft brush or pumice stone if the limescale is difficult, and don’t use abrasive tools. Fill a plastic bag with white vinegar and tie it around the showerhead. Leave it for several hours and scrub gently.

Rust restoration

Handle rust with commercial rust removers and allow them to work for some minutes before wiping clean. Alternatively, you can use a DIY solution made of lemon juice or baking soda paste. Scrub them gently with a cloth after letting them sit for a few minutes.

Protect metal fixtures from future rusting by polishing the metal fixtures with a gentle metal polish—Minimise moisture buildup by regularly drying wet surfaces.

Drain odours & blockages.

Use a plunger or a drain snake to clear minor blockages in bathtubs, sinks or showers. To remove difficult clogs, pour half a cup of baking soda down the drain, followed by half a cup of vinegar. Flush with hot water after letting it fizz for 15-30 minutes.

Neutralise unpleasant drain odours with baking soda and vinegar solutions, and for persistent smells, use enzymatic drain cleaners. Regularly clean drains with hot water and a natural cleaner (vinegar) to prevent future clogs and odours. You should also install filters to keep your drains smelling fresh and prevent debris buildup.

Get a showroom look with the final touches

Make the space look “never used.”

• Use a microfiber cloth and gentle polishing product to remove soap scum, fingerprints, and water spots from handles, taps, and shower heads.
• Remove smudges and gate a crystal-clear look on mirrors and glass surfaces with vinegar-water solution or a streak-free cleaner
• Use a grout cleaner to make grout lines spotless
• Thoroughly clean shower curtains or screens or replace them for a fresh look.

Disinfect high-touch areas

• Use an alcohol-based cleaner or disinfectant wipes to clean all door handles and light switches
• Disinfect flush handles with a multi-surface cleaner
• Wipe down faucets and taps with an antibacterial cleaner for a germ-free finish
• Wipe down vanity counters and crevices

Fresh air strategy

• Open windows and turn on the extractor fan to remove lingering moisture and refresh the air
• Use an essential oil diffuser or eco-friendly air freshener to give the space a light, fresh scent
• For persistent musty smells, use activated charcoal or baking soda in corners.

Final walkthrough checklist

• Examine all surfaces and see if you missed any spots or found streaks
• Test faucets and flush toilets
• Check out corners and edges for left dust or grime
• All glass surfaces and mirrors should be streak-free
• Make sure the bathroom smells fresh.

How to maintain the sparkle—tips for tenants

Daily routines

After each use, wipe down sink faucets, countertops, and bathroom surfaces so that toothpaste, soap scums, water spots, and grime don’t build up. Use a squeegee on the walls and glass after showering to prevent soap scum and limescale buildup. Put away toiletries and clear countertops of personal items to always keep the bathroom tidy and organised.

Weekly maintenance

Use a multi-surface cleaner to wipe down toilets, bath sinks, and vanities and remove dust and grime. Make mirrors and glass surfaces a nice shine with a streak-free cleaner, and scrub grout lines and tiles once a week.  Check out for mould around shower corners or under sinks.

When to call the pros

If mould spreads in difficult-to-reach areas and regular cleaning doesn’t work, hire professionals for mould removal. Call in the pros to tackle severe limescale—they will use industrial-grade descalers and tools. Clogged drains (sinks and showers) may also require professional servicing, and you should hire pros to remove rust from fixtures.
