Church Cleaning Checklist: Pews, Stone Floors, Brass and Stained Glass

A church is the hardest building on our list to clean well, and the easiest to damage by cleaning badly. The same room can hold a Victorian encaustic tile floor, lime-plastered walls, oak pews with a hundred years of wax, brass that has been polished every week since the Great War, and stained glass that must not be touched with anything wet. A product that is right for one of those ruins another. The checklist below is organised by material rather than by room for that reason, and it separates the jobs a volunteer rota can do from the ones that need a contractor with the right equipment.

It is the list we work from on church cleaning in London contracts, and it applies with small changes to chapels, meeting houses and any historic place of worship.

First principle: know what you are cleaning

Before anyone touches a surface, find out what it is. A listed church will have a quinquennial inspection report from the architect that names the floor, wall and joinery materials; the churchwarden usually has it. If in doubt, treat every surface as the most fragile version of itself: stone as soft, wood as waxed, metal as lacquered, glass as painted. Dry methods first, water second, chemicals last and only where the material is known.

Stone and tile floors

Encaustic and quarry tiles, flagstones, marble and terrazzo all appear in London churches, often in the same building.

  • Daily or weekly: sweep with a soft brush or vacuum with a soft-floor head. Grit is what scratches; remove it before anything wet.
  • Damp mop with clean water and, at most, a pH-neutral stone soap. Never a supermarket floor cleaner, never bleach, never anything acidic. Vinegar etches marble and limestone and strips the fired surface of encaustic tiles.
  • Do not seal, wax or polish historic tiles or stone without the architect’s agreement. Modern sealants trap moisture in the floor and cause the surface to spall.
  • Candle wax comes off with a plastic scraper after cooling, then a cloth with a little white spirit on stone; never scrape with metal.
  • Salt bloom (white powder on flagstones near doors or damp walls) is brushed off dry. Washing it in drives the salt back.

Wood: pews, screens, doors and floors

  • Weekly: dust with a soft cloth or a vacuum with a brush head, including under the seats and along the kneeler rails where dust collects.
  • Quarterly: wipe with a barely damp cloth and dry immediately. Water left on oak raises the grain and leaves white marks.
  • Annually: a thin coat of a good quality paste wax on pews and doors, buffed off. Not silicone spray polish, which builds a film that cannot be removed and that conservators dislike.
  • Timber floors are swept and damp mopped like stone; waxed boards get a paste wax once a year.
  • Chewing gum and sticky residue under pews is frozen with a freezer spray and lifted with a plastic scraper.

Brass, bronze and other metalwork

Lecterns, altar rails, memorial plaques, candlesticks and light fittings. Two questions first: is it lacquered, and is it a memorial? Lacquered brass needs only dusting and a wipe; polishing strips the lacquer and starts a cycle that never ends. Memorial brasses set into the floor or wall should not be polished at all; dust them and leave them. For unlacquered brass that has always been polished, a non-abrasive brass cleaner on a cloth, applied to the cloth not the object, with the surrounding stone or wood masked so the polish does not stain it. Monthly is plenty; weekly polishing wears the engraving away over decades.

Stained glass and plain glazing

Stained glass is painted on the inside face and the paint can be loose. Do not wash it. Dust the leads and the inside face with a soft brush once or twice a year and nothing more; anything beyond that is a conservator’s job. Plain glazing, porch windows and glass doors are cleaned normally with water and a squeegee. Window ledges and the deep stone sills under windows collect dead flies and dust and are a weekly task.

Walls, ceilings and high-level areas

Lime-washed and lime-plastered walls are dusted, never washed. Cobwebs are removed with a long-handled soft brush or a vacuum on a pole; in a high nave this is a job for a contractor with telescopic poles or access equipment, done once or twice a year. Painted walls in halls and vestries are washed normally. Ledges, cornices, the tops of screens and the backs of organ cases hold decades of dust and are the usual source of the “dusty church” smell; an annual high-level clean deals with it.

Textiles

Kneelers, pew cushions, altar frontals, banners, carpets and curtains. Vacuum kneelers and cushions on a low setting through a mesh screen so the fabric is not pulled. Altar frontals and banners are not for the cleaning rota; dust them lightly and refer anything more to a textile conservator. Carpets in aisles and the nave are vacuumed weekly and hot-water extracted once a year, more if the building is used for lunch clubs or a nursery during the week. A church carpet runner is the same job as any other commercial carpet cleaning in London, with care taken not to over-wet the floor underneath.

Halls, kitchens and toilets

The parts of the building let for toddler groups, elections and concerts are cleaned like any public venue: toilets daily when in use, kitchen surfaces and the floor after every booking, bins emptied, touch points wiped. A church kitchen used to serve food is subject to food hygiene law and may be inspected; it needs the same cleaning schedule as a café, with the oven and extractor on a termly deep-clean list.

Volunteer rota or contractor?

Most parishes run on a rota of volunteers who sweep, dust and do the flowers, and that is fine for the weekly tasks above. The jobs that go wrong on a rota are the ones that need equipment, height, time or product knowledge: high-level dusting in the nave, machine scrubbing of a tiled floor, carpet extraction, the annual pew wax, cleaning after building work, and the deep clean of a hall kitchen. Those are the tasks to contract, on a quarterly or termly basis, with a written list of what will and will not be done to each surface. A contractor who turns up with a bleach mop and a can of silicone polish has not understood the building; ask what they will use on the floor before they start.

The same rules, with their own sensitivities, apply to mosques, synagogues, temples and gurdwaras. Prayer carpets in particular are a specialist job, covered in how to clean prayer mats and mosque carpets.

A printable summary

  • Weekly: sweep and vacuum floors; dust pews, ledges and sills; toilets and kitchen if used; bins.
  • Monthly: damp mop stone and timber floors; polish unlacquered brass; vacuum textiles; clean plain glass.
  • Quarterly: wipe woodwork; wash hall walls and painted surfaces; deep clean the hall kitchen and toilets.
  • Annually: high-level dusting; pew and door wax; carpet extraction; dust stained glass leads; machine clean tiled floors (with the architect’s agreement on products).
