Hi Guys
Need a bit of help, been asked to clean a copper roof with 5 glass sky light lights but it's got a fair bit of birds poo on it. Was thinking of jet washing it but been to look at it today and its on the 5th floor with scaffolding all around it with no power pionts in the building as all the power has been ripped out for refub works.
so my next option is to wfp it but not sure whats best to wash it with first
Any help would be great
Thanks
Ryan
