    Hi,

    I was gone from my house for a few months and during that time there was a lot of heavy rain which has left the circular stains on the windows as you can see in the image attached. I have tried scrubbing with hot water and soap, even with a decal product which did not do much good. Any ideas on how I can get rid of this from the windows?

    Many Thanks

    Colm

    Worked for me in the past. Used it on a window that had a bog overflow over it. Came up a treat, no hard work involved :)
