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 alike counsel a clear sense of where to stop. Read together, their guidance suggests a hierarchy of intervention: dry removal is routine, washing is conditional, and repairs call for a conservator. Most of it concerns older pieces and glass objects generally. For a contemporary fitting, the maker’s own instructions come first.

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

A chandelier’s metalwork calls for as much consideration as its glass. Reilly and Mortimer, writing in the Journal of the American Institute for Conservation, ask that the metalwork be identified first, since mounts may be gold-plated or finished in a tinted spirit-shellac lacquer to imitate gilding. The materials used to colour or patinate the metal should be fully understood before any treatment is planned.

Handling the glass

The V&A’s conservators name handling as the main risk to glass. Rings, bracelets and watches should be removed, each piece examined on a padded surface, and fragile glass never held by its handle or rim, which may be a weak point.

If a piece breaks

Every fragment should be collected, however small, and no attempt made 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. 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, with a soft bristle brush rather than a cloth, which may snag on fragile surfaces. At the Reggia di Caserta, the royal palace near Naples, the cleaning specification for the chandeliers calls for a museum vacuum.

Why washing is different

Washing here means any use of water or a cleaning solution, from a dampened swab to immersion, and it can do harm in several ways. 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. 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.

Wet cleaning is a different order of intervention, and it does not follow automatically from dusting. Where water is used, distilled or deionised water is preferable to tap water, particularly 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.

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.

Unfired gilded or painted decoration may appear fragmentary, or be lifting or flaking. Deteriorating glass feels slippery and looks dull, patchy or fogged, and forms droplets of liquid in damp conditions. Very fine surface cracks, known as crizzling, may deepen until the glass flakes. Deterioration is typically associated 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.

Lessons from the great houses

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. For metals, glass and porcelain, the Trust recommends soft pony-hair brushes. Few private owners have that time or staff, but the principle carries over: gentle, patient and piece by piece.

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. Water or detergent can also stain a fabric shade or loosen the cloth 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. Finer fabrics such as silk are generally safer kept dry, and a mark that has settled into the weave tends to stay there. Many shades are silk, which breaks down over time through light damage.

Here too, dust is removed dry, with a soft brush, a lint roller or a vacuum on its lowest setting. Textile conservators go a step further and lay a piece of open-weave gauze over the nozzle.

Water remains the difficulty. The Canadian Conservation Institute does not recommend washing historic textiles of wool or silk, and asks for a colourfastness test before wet cleaning is even considered. Most published guidance of this kind concerns historic textiles rather than shades in use, so it shows 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. Washing, dry cleaning and spot cleaning are best left to a trained textile conservator, and Icon’s directory can be searched for textile specialists.

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, from glass and shade alike. Treat washing as a decision about a particular piece, and know the point at which household cleaning should stop. The aim throughout is the least intervention that the materials can safely tolerate.
