<p>A method of removing a polymer from an object, such as a part of a mixing device comprises: a) providing an aqueous solution containing a glucoside and a glycol, b) placing the solution in a chamber (15) to which air is supplied under pressure so that said solution is caused to flow along a line (33) leading to the object so as to impinge on the object, c) introducing air into the solution as it flows along said line so as to effect frothing of said solution prior to application thereof to the object, and d) continuing to supply air under pressure to said chamber after the solution has been discharged from the chamber so that, after the solution has been applied to the object, air under pressure is applied to the object to effect drying thereof. <IMAGE></p> |
