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. |
