Cleaning a bathroom

Bathrooms accumulate three distinct problems — limescale, soap residue and mould — each requiring a different approach.

Limescale

Mineral deposits from hard water, appearing as chalky white or grey build-up on taps, screens, tiles and inside kettles and showerheads.

It is dissolved by acid, not by detergent, which is why scrubbing achieves little.

Vinegar or a citric acid solution works for light deposits; proprietary descalers for heavier ones.

The technique that matters: contact time. Applying acid and wiping immediately does nothing; leaving it for fifteen minutes or longer does the work.

For taps and showerheads, a bag of vinegar tied around the fitting overnight is the standard approach.

The caution: acid damages natural stone, some enamel and some metal finishes.

Check what a surface is before applying anything acidic, and never combine acid with bleach.

Soap scum

A different deposit, formed by soap reacting with minerals in hard water, producing a greasy film.

It responds to detergent and to mild abrasion rather than to acid alone.

A cream cleaner or a detergent with a non-scratch pad removes it.

The preventive measure is more effective: switching from bar soap to liquid substantially reduces its formation, and squeegeeing a shower screen after use prevents both this and limescale almost entirely.

Mould

Which grows where surfaces stay damp, principally in grout, in sealant and on ceilings.

Removing it requires a fungicidal product or a bleach solution, applied and left for the stated contact time.

Sealant that is heavily colonised generally cannot be cleaned successfully, because the growth is within the material, and replacing it is the durable answer.

The cause is ventilation, discussed elsewhere on this site, and cleaning alone means it returns within weeks.

Which makes an extractor fan, used during and for a period after showering, the actual solution.

The order of work

A sequence that works.

Ventilate and clear surfaces.

Apply products that need contact time — descaler on taps and screen, cleaner in the toilet — and leave them.

Clean from top down: any ceiling mould, then tiles and screen, then basin and bath, then toilet, then floor last.

Rinse thoroughly, since residue attracts dirt and leaves streaks.

Dry surfaces, which prevents new water marks and is what produces the finished appearance.

The specific items

Showerhead: descale periodically, since blocked jets reduce flow and harbour deposits.

Drains: hair and soap accumulate, and clearing them mechanically with a drain tool is more effective and less damaging than chemical drain cleaners, which are hazardous and can damage older pipework.

Toilet: a brush and a cleaner under the rim, with contact time.

Limescale below the water line requires acid and, for heavy deposits, lowering the water level first so the descaler is not diluted.

Grout: a stiff brush and a suitable cleaner. Discoloured grout can be renewed with a grout pen or, for a lasting result, raked out and replaced.

Extractor fan: the cover removed and cleaned periodically, since a clogged fan moves very little air.

The habits that reduce the work

Where the largest gains are.

Squeegee the shower after use, which takes twenty seconds and prevents most limescale and soap scum.

Run the extractor during and for twenty minutes after showering.

Leave the shower door or curtain open to dry.

Wipe basin and taps after use.

Wash bath mats and shower curtains regularly, since both harbour mould.

And deal with any leak promptly, since a slow drip is the source of a great deal of bathroom damage.

The safety points

Ventilate when using strong products.

Wear gloves.

Never mix bleach with acidic descalers or with anything containing ammonia.

And store products out of reach of children, since bathroom cleaners are among the more hazardous items in a household.

Ventilation, which does more than cleaning

Most recurring bathroom problems are moisture problems rather than dirt problems.

Mould on sealant and grout, peeling paint, musty smells and condensation on walls all trace to humid air that has nowhere to go.

Which means the extract fan should run during and for a period after bathing, the window should be opened where there is one, the door should be kept closed while the room is humid so moisture does not spread through the house, and wet towels should be dried elsewhere rather than left in the room.

A fan that is noisy, weak or disconnected is a common finding, and replacing one is inexpensive relative to what humidity costs in decoration and repair.

General information only, not safety advice. Never mix cleaning products, follow label instructions, and contact emergency services or a poisons service if exposure occurs.
