A few areas of my round suffer badly with swallow mess (the small yellow marks) cleaning the glass Traditional was never a problem as it just scrapped off. But I changed over to wfp end of last year and now the swallows are back i find that I can't remove their mess no matter how much I soak and scrub! Does anyone have an idea of what to use to remove it please?
Thanks.
