The invention relates to compositions and methods for reducing biocontaminant (for example flesh, blood, mucous, faeces or biofilm) on a surface, such as an endoscope surface. The compositions are viscoelastic and of low lubricity, having the following properties at 21° C.: a rotational yield point between 140% strain and 300% strain; a peak viscosity between 550 Pa·s and 2000 Pa·s; an oscillatory flow point between 250 and 700% strain; and a coefficient of friction μ which has a maximum value (preferably 0.06 or greater) in the viscoelastic liquid's elastohydrodynamic region.
A method of reducing a biocontaminant on a surface contaminated therewith comprising contacting the surface with a viscoelastic liquid and flowing said viscoelastic liquid along said surface thereby to remove said biocontaminant from the surface, wherein the viscoelastic liquid has the following properties at 21° C.:
