Remove limescale (chalk, white stains) from a facade, wall or brick.

Most houses in the UK are covered with salt stains or limescale on their fronts and walls. A salt breakout makes white chalk stains / deposits on bricks. A revolutionary product that can help remove these stains completely is Ecocal.
Below you’ll find a guide on how to remove limescale and chalk stains from facades, walls and bricks.

Equipment / materials
Remove white stains and limescale with Ecocal - before and after

  • Brush (non plastic)
    The best material to apply Ecocal with is a brush.
  • Protective clothing and gloves
    There is no need to wear protective clothing since Ecocal is human- and environmental friendly. You may however put on rubber gloves, seeing the alkaline (degreasing) nature of Ecocal.

Step-by-step guide for the removal of limescale / salt blowout (chalk, white stains)

  • Make sure that the surface is free from oil, paint or other sealing materials.
  • Immerse the brush in the Ecocal and apply it from bottom to top. When cleaning a big surface, it is advisable to divide the area in sections.
  • As soon as Ecocal has been applied, let it do its work until the foaming gets less. Then rinse the area with a garden hose, or high-pressure cleaner and water (5 – 15 min).
  • In case of persistent stains, the treatment should be repeated until the salt blowout has disappeared completely (1 to 3 times should be sufficient).

Tip: Depending on the kind of job, you can dilute EcoCal 1:40 with water.
