Sustainable cleaning agents for removing green deposits

If you want to use environmentally friendly alternatives, you can use special cleaning agents such as our Biosativa®cleaning concentrate. These often contain biodegradable ingredients that effectively remove green deposits without harming the environment. The big advantage: depending on the severity of the stain, you can mix the concentrate and leave it to take effect. The cleaner is also suitable for use in high-pressure cleaners. Pay attention to the application description here.

How can green deposits be removed and prevented?

Impregnations or sealants can be used to effectively prevent green deposits. These products form a protective layer on the surfaces that prevents the penetration of moisture and thus the formation of green deposits. Regular impregnation is particularly useful for wood and stone surfaces.

Prevent green deposits with (nano) impregnation or (nano) sealing

Impregnations or sealants can be used to prevent green deposits in the long term. Our products can form a protective layer on the surfaces, which makes it more difficult for moisture to penetrate and can therefore reduce the formation of green deposits.
However, the actual effectiveness depends on the specific environmental conditions and regular maintenance. Regular treatment is particularly advisable for porous materials such as natural stone or concrete.

For outdoor areas in particular, it is important to regularly use impregnation to protect surfaces from environmental influences such as moisture, frost and sunlight. This not only prevents green deposits, but also increases the durability of the treated surfaces.

Which household remedies are suitable for removing verdigris?

The correct use of household remedies can also help effectively against unsightly stains. Below you can find out which household remedies and methods can be used if you want to remove the unsightly green deposits.

Using vinegar to remove verdigris

Vinegar or acetic acid can be an effective household remedy for removing verdigris from copper or brass surfaces. However, only use vinegar in diluted form and test it on an inconspicuous area first to ensure that the surface is not damaged. The acidic property of vinegar helps to dissolve the oxidized layer of verdigris and clean the surface. Simply apply vinegar essence, leave to work and then wipe off thoroughly.

Remove green deposits with soda

Soda is a versatile household remedy that can also be used to remove verdigris. A mixture of soda and water can be applied to the greenish discoloration and gently rubbed in.
The treatment should be repeated regularly and the surface re-treated to prevent the formation of new green deposits. After a short exposure time, the surface can be wiped with a damp cloth to remove the verdigris.

Thanks to its cleaning properties, soda is a gentle alternative for removing moss and lichen from sensitive surfaces such as copper or brass. Regular applications can help to reduce the formation of new verdigris.

Removing moss, algae & co. with baking soda

Baking soda is not only an effective agent against verdigris, but also against moss, algae and other contaminants in outdoor areas. Mix baking soda with water to form a paste and apply it to the affected area. After a short exposure time, the paste can be wiped off with a soft brush or cloth.

The disinfecting effect of baking soda not only removes visible dirt, but also eliminates spores and germs. This not only removes the green deposits, but also prevents them from forming again.

Effectively remove verdigris with pelargonic acid

Pelargonic acid is a natural acid that can be used effectively against verdigris on terraces, facades and other exterior surfaces. Apply a solution of pelargonic acid and water to the affected areas, leave to act briefly and then rinse thoroughly to remove the verdigris.

Removing verdigris from patio slabs

Verdigris on patio slabs can be effectively removed using various household remedies and cleaning methods. One option is to use warm water with baking soda. Apply a mixture of baking soda and water to the patio tiles, leave to soak in and then scrub thoroughly with a brush or sponge.

The easier way would be to use our Biosativa®cleaning concentrate, as you can leave it to take effect. The sustainable and excellent cleaner is particularly effective against unsightly stains.

Alternatively, the use of vinegar can also help. Apply vinegar essence to the affected areas and leave to act for a few hours. Then rinse the patio slabs with clear water to remove the dissolved verdigris and clean the surface.

Tips for avoiding green deposits on wooden surfaces

Green deposits on wooden surfaces can be effectively reduced by targeted measures. It is important to regularly remove leaves and other dirt from wooden surfaces to prevent damp patches from forming. Regular sweeping and cleaning can prevent moss, algae and other impurities. You can also impregnate the wood surface with a nano sealant to protect it effectively.
