A stone wall adjacent to my house has been graffiti-ised the other day with what looks like aerosol paint. What is the best quick way of getting rid of it? The stone appears to be quite hard.
It is an old stone wall along a railway line but it's pointless expecting that NetworkRail will be interested in cleaning it off. The quickest way is to try to get rid of it myself especially as its presence is likey to attract more of the same.
Thanks
Steve.
