1. 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.:
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 in the viscoelastic liquid's elastohydrodynamic region.
