<p>A special device for cleaning of air vent screws (2) is constituted by a holder (8) with a head part (9), and a mop (11), where the mop is tailored to the head part, the head part (9) and mop (11) are especially designed for complementary adaptation to the shape of an air vent screw (2). The shape of head part (9) and mop (11) is also so that a section (12, 13) extends into the conically shaped opening (4) of the air vent screw, on the inside/outside of the adjustable air flow controller (6) of the vent. Washing is performed by fitting the device against a vent (2), and a rotary motion to absorb dirt from the surfaces (7, 4, 10) of the vent with the mop (11).</p> |
