How to Clean a Chandelier and Its Shades

Guidance from conservators and makers

Dust settles on a chandelier, and cleaning one is largely an exercise in restraint. A chandelier is seldom one material. Glass hangs from brass or bronze that may be gilded or lacquered. The parts are joined by pins and sometimes by adhesive, earlier repairs may be present, and a lampshade adds fabric, laminate and adhesive. Every method of cleaning puts something in that assemblage at risk, and caring for one begins with understanding what it is made of.

Before any cleaning begins, the fitting should be switched off and, where it is plugged in, unplugged, as the Health and Safety Executive advises for appliances. Work on the electrics themselves is a matter for a qualified electrician.

Conservators and makers repeatedly counsel restraint and a clear sense of where to stop. Conservation guidance names the conditions in which a specialist should be consulted about cleaning, among them repairs, metal mounts and unfired gilded or painted decoration. Makers, who know how a shade or a fitting is built, observe that water can affect the adhesive in a shade. Cloth, they add, may come away from its support. What follows draws on published advice of both kinds. Most of it concerns older pieces and glass objects generally. For a contemporary fitting, the maker's own instructions come first.

Read together, the guidance suggests a hierarchy of intervention. Dry removal is routine. Washing is conditional. Repairs call for a conservator.

Before you clean: identify, photograph and label

Before anything is touched, document the piece. Reilly and Mortimer, writing in the Journal of the American Institute for Conservation, advise that good photographs and sketches be prepared. When the chandelier in its Cinnamon Drawing Room was cleaned at Harewood House, a plan of it was drawn and labelled bags were prepared for all the parts. 

Identify the metalwork

Because a chandelier is an assemblage, its metalwork calls for as much consideration as its glass. Reilly and Mortimer ask that the metalwork be identified first, since mounts may be gold-plated or finished in a tinted spirit-shellac lacquer to imitate gilding. They add that the materials used to colour or patinate the metal must be completely understood before treatment is planned.

Handling the glass

The V&A's conservators name handling and other interactions as the main risks to glass. They ask that rings, bracelets and watches be removed, and that each piece be examined on a padded surface. The National Trust cautions against holding fragile glass by its handle or rim, which may be a weak point.

Specialists do not always agree on gloves. Mallory Custom Lighting, in a published account of cleaning a large chandelier, says that lint-free cotton gloves help. The V&A suggests thin disposable rubber gloves when examining glass. The Canadian Conservation Institute (CCI) advises against gloves for glass, and Reilly and Mortimer caution that fabric or plastic gloves may catch on protruding pins and fittings.

If a piece breaks

The V&A advises collecting every fragment, however small, and resisting any attempt to fit the pieces together, since the edges are fragile. The broken edges should be touched as little as possible, because fingermarks can interfere with bonding. It adds that, if the glass is worth repairing, professional advice should be sought.

Dry removal: the safest routine

As a first principle, loose dust is removed dry. The CCI recommends a soft bristle brush and cautions that a cloth may snag on fragile surfaces, and the Reggia di Caserta specifies a museum vacuum for its chandeliers.

Why washing is different

Wet cleaning is a different order of intervention, and it does not follow automatically from dusting. Where water is used, the kind matters. The CCI accepts tap water but prefers distilled or deionised, and the V&A's conservators recommend distilled water in hard-water areas. At Harewood, each piece was cleaned with a cotton swab dipped in deionised water and then dried carefully with paper towels. 

Washing here means any use of water or a cleaning solution, from a dampened swab to immersion. The sources name several ways in which it can do harm. Water or solvents can damage mounts fixed with plaster or adhesive. High temperatures, high-pressure water and aggressive detergents can attack the surface of glass, which is why the V&A advises against the dishwasher for historic or valued pieces. The Reggia di Caserta requires any washing of its chandeliers to be agreed in advance with the project manager. Whether to use water at all depends on the piece's materials, construction and condition. Even distilled or deionised water does not make washing suitable for every piece.

When to stop and call a conservator

The V&A's glass conservators set out the circumstances in which a specialist should be consulted about cleaning. Household cleaning should stop at each of these points:

  • metal mounts;
  • repairs;
  • signs of deterioration;
  • unfired gilded or painted decoration;
  • flaking or lifting enamel.

The V&A notes that unfired gilded or painted decoration may appear fragmentary, or be lifting or flaking. Deterioration shows as glass that feels slippery and looks dull, patchy or fogged, and that forms droplets of liquid in damp conditions. Very fine surface cracks, known as crizzling, may deepen until the glass flakes. The leaflet associates deterioration typically with sixteenth-century Venetian and seventeenth-century cristallo glass, though other types can also be unstable.

If any of these conditions are present, or merely suspected, cleaning should go no further. Icon, the Institute of Conservation, runs a Find a Conservator directory, searchable by specialism and location.

Routine care

Institutions keep to a rhythm. Some National Trust houses close for the winter to be cleaned in depth; at Chartwell, each chandelier is taken down and taken apart so that every crystal and link can be cleaned individually, with a cotton bud passed over each piece. The Trust also recommends soft pony-hair brushes for metals, glass and porcelain. A house that closes for the winter has time and staff that a private owner lacks, so its practice illustrates a principle and is not a routine for a private home.

Fabric shades

A shade calls for its own approach, because its construction brings in materials that respond very differently to moisture. Iberian Lighting, a maker of handmade shades in Hastings, explains that hard shades are built in layers of fabric, laminate and adhesive, and that once water enters the panel it can begin to affect the adhesive. The Italian maker Horus Paralumi advises against wetting a fabric shade with water or detergent, because the cloth may stain or come away from its rigid support. Where a maker's instructions survive, they come before anything written here.

The fabric and its age matter as much as the construction. Iberian says that finer fabrics such as silk are generally safer kept dry, and that a mark that has settled into the weave tends to stay there. The United States' National Trust for Historic Preservation, in its manual on housekeeping for historic houses, notes that many shades are silk, which it says breaks down over time through light damage.

Dust is removed dry. The same manual advises vacuuming or brushing carefully, and Iberian a soft brush, a lint roller or a vacuum on a low setting. For historic textiles, conservators advise removing loose dust before any other treatment. The Western Australian Museum recommends a vacuum with adjustable suction and a soft brush, and the Australian War Memorial the lowest suction setting with a piece of open-weave gauze over the nozzle.

Water remains the difficulty. The CCI does not recommend washing historic textiles of wool or silk, and requires a colourfastness test before wet cleaning is considered; the Western Australian Museum states that textiles should not be washed as a matter of course. Apart from brief remarks in the National Trust for Historic Preservation's manual, the guidance we found concerns historic textiles, not shades in use on lamps, and so indicates the direction of practice rather than a method.

For a shade of historic or artistic importance, or one that cannot be replaced, the principle that runs through this guide applies: valuable or vulnerable material deserves specialist assessment. The Australian War Memorial, writing of historic textiles, reserves washing, dry cleaning and spot cleaning to a trained textile conservator, and Icon's Find a Conservator directory can be searched by specialism, textiles among them.

In short

A chandelier is a collection of materials with different vulnerabilities. Identify what is there, and photograph it before anything is touched. Remove loose dust dry, with a soft brush and a vacuum. Treat washing as a decision about a particular piece. Where there are metal mounts, repairs, signs of deterioration, unfired gilded or painted decoration or flaking enamel, stop and consult a conservator. A hard shade is built in layers of its own, and the maker's instructions come first. The aim throughout is the least intervention that the materials can safely tolerate.
