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
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.
