Shower, bath, screen: tackling limescale

The bathroom is the room where guests are most critical, because it’s the only one where they get undressed. A shower screen clouded with limescale, a grey joint, a drain that smells: three details that can ruin a review, and all three come from the same thing, water left to dry where it sits. This guide gives you the right actions, how often to do them, and which products to avoid.

What needs doing, and how often

The shower screen: the one move that changes everything

Limescale on a screen isn’t from lack of product, it’s from water left to dry on it. Every evaporated drop leaves its minerals behind, and the layer builds up until no spray can get through.

The routine treatment, every clean:

1. Clean with a gentle productOr with vinegar water if the screen is untreated glass.
2. Rinse.
3. Squeegee from top to bottomThen dry with a microfibre cloth. It’s this last step, and only this, that gives you clear glass.

If a limescale film is already there, warm white vinegar on a cloth left for ten to fifteen minutes will dissolve it; repeat rather than scrub. Abrasive scrubbing scratches the glass, and scratched glass collects limescale twice as fast.

Two things to avoid: limescale-treated screens, where vinegar damages the coating (use only soapy water, the property’s guide should say so), and aluminium joints on some cubicles, which acid will corrode.

The move that halves your work all season: leave a squeegee in the shower with a little note inviting guests to use it. Some will, and those who don’t won’t mind you asking.

The joints, and why they go black

A silicone joint that goes black isn’t dirty: it’s colonised by mould growing inside the material. Surface cleaning won’t reach it.

The method that works, monthly or as soon as black spots appear:

1. Soak kitchen paperOr cotton wool in a diluted bleach solution or a specialist joint gel.
2. Lay it directly on the jointAnd leave for one to two hours. It’s the long contact that works, not the strength.
3. Rinse thoroughlyAnd ventilate throughout.

Never mix this with descaler or vinegar: the reaction releases chlorine gas, dangerous in a closed room. Rinse completely between products.

If the joint stays grey after two treatments, it needs replacing, not cleaning. A silicone joint can be replaced in an hour and gives a shower another ten years.

The drain, the real source of odour

Bathroom smells almost always come from the shower drain, rarely from surfaces. Under the grate, a mix of hair, soap and limescale builds up and ferments.

Every four cleans:

1. Lift the grateUsually just placed or fixed with a central screw.
2. Remove the gunk by handWith a hook or pliers. No product dissolves hair.
3. Scrub the basket and collar.
4. Pour in bicarbonate then white vinegarLeave for ten minutes, then a litre of very hot water.

Avoid chemical unblockers for routine maintenance: they damage joints and old pipes, and don’t solve the physical blockage.

With a rarely used shower, the trap dries out between stays and lets drain smells up: pour half a litre of water down each drain at the end of the clean, including any spare bathrooms.

The bath

Clean the bath itself with a gentle, non-abrasive product, paying attention to the waterline, where a greasy soap film builds up. On acrylic, never use powder or scouring pads: micro-scratches dull the finish and trap dirt.

Three areas a quick clean always misses:

• The edge and wall joint, where water sits.
• The overflow, whose collar usually unscrews, and which smells if never opened.
• Under the mixer and the hose, where limescale builds up out of sight.

Taps, and the only secret to shine

Shiny taps don’t come from any product: they come from drying after rinsing. A tap washed and left to dry keeps the marks from the water itself.

For a mixer with limescale, wrap it in a cloth soaked in warm white vinegar, leave for thirty minutes, then scrub with a soft brush and rinse. The aerator at the spout unscrews and can be soaked separately: it’s what causes a wonky spray or low flow, never the mains pressure.

Two warnings: matt black, brushed brass or copper finishes can’t take acid or abrasives, only soapy water and drying. And on chrome, never use a scouring pad, which leaves permanent micro-scratches.
