DO NOT TRY TO REMOVE GRAFFITI WITHOUT SEEKING PROFESSIONAL ADVICE! It may well make things worse and more expensive in the long run.
It is very tempting to pop down to your local DIY centre, pick up an off-the-shelf solvent and attempt removal yourself. However, there is a very high possibility that it will push the stain deeper into the surface leaving you with permanent damage.
Painting over the graffiti sounds like an easy option, but in reality the solvents in the paint cause the graffiti to ‘grin’ through the paint and you will end up painting over the same area time and time again.
