The post you are reporting:
Paul, I came to the conclusion that the graffiti in the Scheduled Ancient Monument must go. Of-course it is difficult getting it off brickwork, impossible to remove it from cement (you can only paint over cement, or add new cement), and extremely annoying removing it from metal, such as doors.
Having past experience of furniture renovation, I know paint can be removed more easily from wood, but even that takes a lot of time and a number of applications before the results are there.
Once graffiti were to be removed from the Heights' infrastructure, it is paramount to make sure no-one goes back and sprays more stuff on the walls, so wardens will be necessary.
Quite clearly, one can't expect visitors to enter areas such as those that Phil has highlighted, so we have to start with the graffiti aspect and the need to prevent more of it appearing.
Your idea of clearing bushes and trees from the entrances and from the brickwork is fine, as not only would it offer less concealment to sprayers, but would also prevent the roots from dislodging the bricks.
It must be said, all this is not work I would recommend as volunteer work, it's not something which could be done on the odd weekend in an improvised fashion, but would need days and days of dire effort just to get ONE wall clean, and that with a number of people working on it.
Removing graffiti also requires an expert with knowledge of how to go about it, and I have no experience in this aspect. I think for bricks you need a a compressor and high-pressure steam pump; they will look new, but this will also alter their original "ancient monument" look.
