Stone conservation treatments (cleaning, consolidation and protection) now most in use in monuments are briefly described and attention is called to the need of carrying out preliminary studies in order to make a correct "diagnosis". The problem of cleaning stones stained by inscriptions is dealt with in a little more detail owing to its present interest.
