Brown Marks on buildings from outlets
« on: February 17, 2015, 11:30:01 am »
You know those brown marks you see from outlets on buildings, normally fairly new properties?  What is that causes it and how do you get it off?  It would really annoy me if it was on the side of my house or flat and totally ruins the look of some buildings.  Thanks.

see if this works;

https://www.google.co.uk/maps/@55.960124,-3.165018,3a,37.5y,28.26h,110.08t/data=!3m4!1e1!3m2!1sLOWiK1zv3O2qrQaJDOx00A!2e0

that should take you to street view, if you look around you will see a brown mark on the tan coloured render coming from the 2nd floor.

yep, rust.

It will lighten with some hypo and a very light pressure wash but I have never got it out completely.

Thanks for the replies.  I did wonder if it was rust.  Any way to stop it from happening?

Tell them to take the central heating out, and block up the hole.

Depending on the render try oxalic having done the RAMS
