Common Questions About Red Algae Cleaning
What is red algae?
Red algae is common in Ireland’s wet climate—especially on north-facing or poorly ventilated surfaces.
Can’t I just powerwash it?
Powerwashing often makes it worse. It doesn’t kill spores and can damage your surface.

Our biocide kills spores and slows regrowth for up to 36 months, depending on surface and conditions.
