That idea, or at least similar, was diss’ed a bit further up this thread so, due to an abundance of ignorance of these things, I’ll give that a miss. 
 

So it seems, however copper sulphate solution was promoted further up this thread so now I’m confused, but as copper was diss’ed I can get my head around copper sulphate solution being a no-no.
 

Yep, shame on me.
 

As they are promoted as self cleaning I thought I wouldn’t have to get involved. I’ve not cleaned them since installation which has got to be pushing 5 years now. It’s not easy to see them and it’s only in certain light you can see what is probably lichen and it was only late last year I spotted it. 
 

Window cleaner is going to cost around £80-£100 to clean them but I wonder if s/he will actually clean the lichen off or just make it wet.

 

Hence the original question. 
 

I assume copper kills lichen (who’d have know!)

 

Also, from what’s posted earlier in this thread I assume copper kills aluminium?

 

It would also seem from previous posts in this thread that copper sulphate solution would kill lichen but not aluminium? 
 

Does copper sulphate solution kill zinc? Anyone know?

Copper Sulphate will damage zinc, so definitely a no no from me. There are Lichen Removal Agrents available as it’s a known problem.
