Abstract
Less viscous liquids (7) such as diesel oil may be unintentionally spread on water surfaces or on the ground (6). Loose sawdust (2) or chemicals are used to clear said surfaces (6). These clearing aids (2) with the liquid (7) absorbed in them are difficult to remove. The use of cases (5) of filter material, filled with sawdust (2) provides an aid which is easy to remove when the liquid has been cleared.
