Clean the facade of the house from algae and moss with cornstarch
Mix 500g of cornstarch, 100g of baking soda and 5L of water to make a paste. Apply the mixture to the house wall or to the individually affected areas. Leave the cornstarch paste on for four hours and then wash it off.
In the case of sensitive facades or sandy plaster, carefully wash off the paste by hand. Use warm water for this, preferably in the early afternoon, so that the facade can then dry well.

Potassium permanganate is actually a wound disinfectant available at the pharmacy that can be used to remove moss.
- Put 5 liters of water in a saucepan and bring to the boil.
- Mix 500 g of cornstarch with a little water to form a paste.
- Then remove the pot from the heat and add 100 g of baking soda, 8 g of potassium permanganate and the cornstarch. Bring the mixture to a boil, stirring constantly.

- Pour the mixture into a bucket and scrub the house wall with it. Leave it on for four hours, then rinse off with a garden hose or pressure washer.
Remove moss and lichen on house wall with bleach
Bleach can be used to remove all types of green growth as it works well as an herbicide and can kill them. However, it is important to use it sparingly and to take precautions as it can damage skin, clothing and other plants.

Prevent moss formation on the house facade
One of the best ways to solve the moss problems is to prevent moss formation. If moss is growing on your house walls, chances are they got wet somehow.
If you have a sprinkler system, you should adjust it this way because it doesn’t hit the front of the house.
Make sure there are no leaking faucets nearby.
Cut back any branches of shrubs or trees that hang over the garden fence as they provide the cool, moist, and shady conditions that the moss needs to thrive.
