A two-part sterilant system comprises a first part comprising a first reagent in a carrier medium and a second part which is miscible with the first part and which comprises a second reagent in a carrier medium. The first reagent and the second reagent will react when mixed to provide a sterilising composition. The first part is contained in a pump dispenser (2) whereby it may be dispensed as a fluid, and the second part is absorbed or impregnated in at least one fabric member (18) in a sealed container (20).
