Algae removal?
« on: November 25, 2005, 10:46:37 am »
Can anyone tell me if there is a secret to removing green Algae on a conservatory roof apart from the WFP and some good old fashion elbow grease?

I am hoping that there is some sort of pre-spray around.

Cheers

TFR will help spray on via a knapsack

A fungicide spray will do it, but you must let it stay on for 2 or 3 weeks to kill the spores if its on a tiled roof conservatory, where they will turn black in colour fall off on their own with the help of rain or light pressure washing.

I just use good old TFR and my brush lance with hot water.
