Moss is almost omnipresent, it grows in the forest and in the garden, on paths and beds, even on trees and bushes and also on the house wall if it is permanently in the shade and/or is damp.

Of course, the moss on a house wall should be removed as soon as possible. But it is also important to get to the bottom of the cause so that the house wall remains free of moss in the future.
Am I allowed to flame a house wall?
We strongly advise against flaming a house wall. For example, a window could burn too easily and set the whole house on fire. A flame torch should never be used overhead because if even a leaf or small twig catches fire and falls to the ground it can start a fire.
Are there effective home remedies against moss on the house wall?
Cola, among other things, is recommended as a home remedy against moss on the house wall. It contains phosphoric acid, which not only kills the moss but also prevents it from growing again. This may work on small areas. However, before you spread the sweet and sticky liquid on a large scale, keep in mind that it will attract ants, wasps, and other insects. However, discoloration is not to be feared.
In addition to cola, vinegar can both remove moss and have a preventive effect. However, since vinegar is harmful to the environment, it should not necessarily be used against moss. Soft soap (44.90€) also removes moss and is less harmful.
Is a pressure washer suitable for house walls?
You can also remove moss from house walls with a high-pressure cleaner (€119.90). However, it may also loosen loose or crumbly plaster. You should therefore use other means to remove moss from plastered house facades. With clinker bricks, on the other hand, the high-pressure cleaner is well suited. In addition, algicides (algae removers) or potassium permanganate are recommended for removing moss.
The essentials in brief:
- Never set fire to house walls
- simplest type of cleaning: high-pressure cleaner
- tedious but effective: wash off with soft soap solution (or vinegar)
tips
If you own one yourself or can borrow one cheaply, then use a high-pressure cleaner to remove moss and verdigris from your clinker house wall.
