Algae Remover, Green Growth Remover, 5 Liter Algae Killer, Concentrate

Yes, the product is suitable for awnings and is gentle on materials thanks to its acid- and chlorine-free formula. It removes green deposits without attacking the color.

The product can be used at lower temperatures as long as the surface to be treated is completely dry. It is important that it does not rain during the exposure time of at least 24 hours.

The cleaner should work for at least 24 hours before you can rinse off any residue. With light soiling and a 1:3 dilution, 5 liters of concentrate are enough for up to 350 m².

Yes, if it rains during the minimum 24-hour exposure time, the treatment of the surface may need to be repeated. The surface must be completely dry when applying.

For very thick soiling such as dense moss, it is recommended to remove it manually beforehand. The remover works automatically when the coarse deposits have been removed.

For heavy green growth, we recommend a dilution of 1:1, i.e. 1 liter of concentrate to 1 liter of water. This ensures the highest effectiveness.

The surface to be treated must be completely dry for the cleaner to work optimally. If it rains during the exposure time, the treatment may need to be repeated.

No, the concentrate must not get into the hands of children and is very toxic to aquatic organisms. It is advisable to prevent access for children and pets during and after use.

You don't have to rinse actively, as the product works automatically. You can rinse off any remaining dirt with water afterwards, or it will disappear on its own with the next rain.

Yes, the green deposit remover can also be used on roofs. Make sure the surfaces are dry before application and observe the exposure time.

In case of heavy soiling such as thick layers of moss, these should be removed manually beforehand. The concentrate then acts automatically on the remaining deposits.

Yes, the product is explicitly suitable for painted surfaces as well as for motorhomes and boats. It is acid- and chlorine-free and therefore very gentle on materials.

Yes, the cleaner is also suitable for natural stone surfaces such as sandstone. The acid- and chlorine-free formula ensures the highest level of material protection.

Yes, the Hotrega Grünbelag-Entferner is suitable for ceramic and glass surfaces. The acid- and chlorine-free formula ensures gentle cleaning of the material.

No, a pressure washer is not required. The cleaner works automatically, so you don't need to use a scrubber or brush either.

The product offers long-term protection against reinfestation, but the exact duration depends on environmental influences. It is indeed acid- and chlorine-free, which guarantees material protection.

The 5-liter concentrate is very economical and is sufficient for approximately 100 to 350 m², depending on the soiling and the surface absorbency. For 200 m², you should dilute it 1:1 to 1:3, depending on the surface, which is usually sufficient. (Roughly calculated: with an average dilution of 1:2 and average absorbency, the 5 liters cover approximately 250 m².)

Apply the diluted concentrate to the dry decking, for example with a sprayer. Let it work for at least 24 hours; do not rinse. Any residue will disappear with the next rain.

Yes, for smaller areas, application with a brush is easily possible. Alternatively, a sprayer or watering can are also suitable.

Yes, the green deposit remover is also suitable for coated and painted surfaces. The special formula is gentle on materials.

Yes, the cleaner works automatically. You do not have to treat the surface with a pressure washer, scrubber or brush.

The concentrate offers long-term protection against new green growth. This reduces the frequency of reapplication.

No, the product is acid- and chlorine-free and guarantees the highest material protection. It is explicitly suitable for awnings and painted surfaces without attacking the color.

Yes, the cleaner is ideal for glass surfaces, including conservatories. It removes green deposits automatically without rinsing.

The concentrate is biodegradable. However, pay attention to the safety instructions, as it is very toxic to aquatic organisms and can cause skin and eye damage.

Thick soiling should be removed manually beforehand. The cleaner then works automatically on the remaining deposits without you having to scrub.

The green stain remover requires an exposure time of at least 24 hours. During this time it must not rain, otherwise the treatment may have to be repeated.

For medium green coating, we recommend a dilution of 1:2. With 5 liters of concentrate, you can treat about 100 to 350 m². For your 150 m² patio, you will therefore need approximately 2-3 liters of the concentrate (roughly calculated: With a 1:2 dilution, the concentrate is sufficient for about 150 m² with medium soiling).

The green growth remover is acid- and chlorine-free and guarantees the highest material protection. It is therefore well suited for wood and plastic surfaces such as WPC.

Yes, the product is very toxic to aquatic organisms (H400). Be sure that it does not get into ponds, water bodies or the sewage system.
