How to correctly clean a Cibox entrance door

What is corrosion?

Atmospheric corrosion is the deterioration and destruction of a metal caused by a mixture of water (rain or condensation), atmospheric oxygen and air pollutants. There are several factors involved:

  • Moisture content (humidity),
  • Rain water which contains mineral elements (acid rain can have a pH as low as 4),
  • Dust which in coastal areas can be full of salt,
  • Fog, which accelerates the corrosive action,
  • Condensation due to the difference in indoor/outdoor temperature,
  • Polluting gas such as chlorine in urban areas,
  • And finally, winter salt for ice and snow on the ground, which can affect the lacquer finish on the lower part of a door.


How to correctly clean a Cibox entrance door

Regularly cleaning a door’s paint coating significantly limits the risk of corrosion. Just simply scrub the door using water and a mild detergent (pH 5-8) and then carefully rinse with clear water and finally wipe it down with a soft absorbent cloth. To avoid scratching or damaging the lacquer layer, do not use any abrasives.

A door should be cleaned in accordance with its geographical location.

  • In rural or scarcely populated areas where the atmosphere does not contain aggressive elements,
    doors should generally be cleaned once a year when the surface is frequently washed by rainwater, and twice a year in drier regions.
  • In urban, industrial or marine environments,
    surfaces exposed to frequent rain should generally be cleaned twice a year, more if there are other deteriorating factors. Parts that are not washed naturally by the rain must be cleaned more often.

Doors can also be washed more frequently if their setting requires them to look immaculate at all times (building entrance, shops, etc.)


Our guarantees

In accordance with the french NF T 36.001 standard, our doors come with a 2-year performance warranty. The finishing treatment on our doors includes a primer (epoxy powder gelled at 160° acting as a shield against corrosion and as an adhesive layer), as well as a finishing coat (textured polyester powder cured at 190° for polymerisation). This process guarantees an extremely durable paint finish, and can repel the effects of salt spray for over 500 hours.

Our recommendation

In areas where the risk of corrosion is high, we recommend choosing the optional stainless steel that is available on all our product ranges.
