  • Do not use any cleaning items that can scratch, have steel or iron in them, or scouring pads – only a soft cloth.
  • Do not use any acids, limescale removers, or any other material based on ammonia or minerals, since these can affect the chrome nickel coating and also the rubber parts.
  • To remove limescale, the area should be soaked with vinegar at 5% for 20 minutes and then rinsed with water.  It is recommended to do this once every 2 weeks
  • In showers with strips – make sure the vinegar does not come in contact with the strips on the external side of the glass.
  • The cleaning of the glass and hinges should be done as follows:  the door needs to stand straight, 180 degrees from the hinge or 90 degrees towards the wall.
  • When the door starts to creak, you should oil the hinge, using Vaseline or baby oil.  The oiling will be done on the round profile through its length, while the door is open at a 90-degree angle.
