Nilco Angel Foam - Patio & Path Cleaner

You should see algae begin to die off within 2 to 4 days after application.

The cleaner stays active, controlling regrowth for up to 9 months.

No, Nilco Angel Foam is only suitable for hard surfaces like stone, concrete, and paving. It is not recommended for wood or other soft materials.

The spray-and-leave format typically does not require rinsing. Allow the product to work and dry naturally on the surface.

While the formulation is acid and bleach-free, it is recommended to keep pets away from the treated area until it has dried to prevent ingestion.

The coverage depends on the concentration of the dirt and algae, and the application rate. The super-concentrated formula is designed to cover substantial areas efficiently.

It is best applied when temperatures are mild and there is no imminent heavy rain, allowing the product to work effectively and dry on the surface.

Ensure the garden hose is securely attached and the water pressure is adequate. Check that the nozzle is not blocked.

Verify that the entire treated area was fully covered by the foam. For stubborn build-up, a second application might be necessary after waiting the recommended period. Ensure the product is within its expiry date.

Although designed to be non-staining, test on an inconspicuous area first, especially on sensitive or previously treated surfaces. Rinse the affected area immediately with water if staining occurs.
