How to maintain my light fixtures?

Spring is in the air and it is time for the annual spring cleaning. Everything is put in tip-top shape for the spring and summer months, both inside and out. Something that is often overlooked during this cleaning is the lighting. It is very important to clean your luminaires regularly. But what is the best way to do this? What should you use and what should you not use? Below, you will find more information and some do's and don'ts!


At Psmlighting, we always produce our indoor and outdoor lighting from high quality materials such as aluminum, brass and stainless steel. In addition, almost all lighting fixtures are available in different powder coating colours. With a correct and regular cleaning of the fixtures, you will be able to enjoy them even longer.


  • Switch off your lighting before you start cleaning.
  • Always use a soft, dry or slightly moist cloth in order not to damage the powder lacquer or varnish.


  • Never use aggressive cleaners containing chemicals such as ammonia or alcohol. Such products affect the surface and colour of the fixture permanently and leave behind permanent damage. If you do want to use a cleaning agent, use one with a neutral pH value.
  • Do not use abrasives to avoid scratching the luminaires.
  • Avoid excessive use of water.
  • Do not clean luminaires in direct sunlight or when they are hot.

Indoor lighting

Indoor lighting fixtures are rarely, if ever, exposed to extreme dirt. Often it is just a matter of dusting or a small spot.

To remove dust, it is best to use a soft, dry cloth. If necessary, you can use a slightly moist cloth, but make sure that it is moistened with clean water. Always dry your fittings well after using water.

Stains are best removed with a slightly moist cloth. Do not rub too hard on the fixture to avoid scratches. Dry your fitting completely after cleaning. Are there any fly droppings? Then do not try to remove them with force. Fly droppings bite into the varnish and cause permanent damage.


At Psmlighting, we have many fixtures with hand-blown glass parts or elements, whether or not coloured glass. Fixtures with glass are a popular trend and a real eye-catcher in your interior, but they also catch a lot of dust.

DO: Always use a dry and soft cloth to avoid scratches.


  • Do not use cleaning products. They can leave permanent marks on the glass.
  • Be careful not to rub the glass too hard.
  • Be extra careful with coated glasses. They have a fragile outer layer that is very sensitive to scratches.


A material that requires extra attention is brass, which is gaining popularity due to its beautiful golden colour. Brass can change its colour over the years under the influence of various factors, such as humidity. For daily maintenance, we therefore recommend always using a soft, dry cloth.

For intensive cleaning, you can use pure water. Do not do this on a regular basis and only when the luminaire has come into contact with dirt.

DON'T: Do not use any aggressive cleaning agents on brass fixtures. They will permanently damage the typical golden colour.

Outdoor lighting

Luminaires that are mounted in the garden, on the terrace, on the façade or on the driveway, regularly come into contact with dirt and harsh weather conditions. The outdoor fixtures at Psmlighting are mostly made of stainless steel or aluminum and are therefore resistant to corrosion and rust. However, this does not mean that our outdoor fixtures do not need to be cleaned regularly.

Also to maintain the life span of the powder coating, luminaires need to be cleaned. The lifespan of the powder coating is negatively affected by dirt, moisture, acids, salts and other aggressive substances. Maintenance recommendations are largely determined by the location and installation of the fixtures.

In general, the same recommendations apply for outdoor luminaires as for indoor luminaires.

  • Do not use abrasive agents that could damage the material or the powder coating.
  • Avoid excessive use of water.
  • Clean surfaces with a dry or slightly moist cloth.
  • Do not use aggressive cleaning products. These lead to stains in the coating and damage the paint finish.

We recommend cleaning outdoor lights at least twice a year. To remove surface dirt, use a slightly moist cloth. Do not rub too hard in order to avoid scratches.

Do you want to use a cleaning product? Then choose cleaners with a neutral pH value of between 5 and 8. There are specific stainless steel cleaners on the market, and you can also get such a product from psmlighting. After using a cleaning product, it is important to rinse the fixture again with clean water and dry it thoroughly with a dry cloth.

Installation on the coast

Luminaires that are installed in coastal areas require special attention. The presence of sand and salt in the air can damage the materials more quickly. We therefore recommend cleaning coastal outdoor fittings at least four times a year. This is best done with a moist cloth to remove the sand and salt particles.

For coastal areas, Psmlighting offers the colour double treated stainless steel (colour code: 5BB). We always recommend this when mounting on the dyke or close to the beach. If you prefer a lacquer colour instead of stainless steel, we can provide an extra primer (at extra cost) under the lacquer layer that protects your fixture better against dirt.

Fixtures close to the ground

Luminaires in plant beds, on a terrace or driveway regularly come into contact with cleaning agents such as bleach or spraying for weeds or vermin, in addition to the normal dirt. If this is the case, the luminaire should be cleaned with pure water immediately after contact with the product in question. Prolonged contact with such aggressive products can cause permanent damage to the paint or the material of the fixture, such as discolouration.
