Got some sun louvres to clean, which we have done previously. They get covered in algae every year.
Last time we used WFP, and they came up nice, just very awkward and back breaking.
Would we be better off with Algoclear?
Is it a matter of spraying and leaving, spraying and rinsing, or spraying and scrubbing?
Also will the Algoclear inhibit future return of algae?
