Cleaning compositions including a photocatalytic material and a sensitiser
employ a photocatalytic material and a sensitiser at a locus, for example
on a surface. The residue combats soils and/or undesired microorganisms
at the locus. The addition of a monohydric or polyhydric alcohol,
preferably having humectant properties, gives benefits in terms of smear
avoidance on application and soil removal thereafter.
