Virosol isn't so bad to get off if it dries out but G 101, StrongArm, (don't know about Ubik) etc, are caustic hard surface cleaners and are not just hard to remove if they dry on the surface on a cool or cloudy day , but in hot weather, they are hell to remove.
Harpic does the job ... or any other toilet cleaner for that matter ... cillet bang, toilet duck ... if it can remove what's in the toilet it can remove algae and grime off a conservatory roof.
