On two of my windows there are stains running down from the top of the
It appears to be coming from the cement round the windows.
I have tried numerous cleaners to try to remove these stains but nothing I
have tried will remove them
Can anyone suggest a remedy please?
Have you tried brick acid? If you're careful you can use a paint brush and
brush the acid on and after a short while wash it off. You could try one of
those kitchen sponges to give the area a nice rubbing after you've applied
the acid but wear rubber gloves!
Been acid you may want to wash it off with a hosepipe which will dilute it
to make it harmless ... just be careful about splashes when putting it on.
Remember it is acid so avoid skin contact and wear old clothes just in case
you do manage to splash it.
