The new design incorporates a stiff handle with a flexible blade tip which makes it easy to apply the correct pressure when cleaning and almost impossible to apply too much pressure. The soft, woven micro fibre is less likely to drop fibres than tissue based swabs. The cleaning material, which wraps completely around the swab tip, is bonded to the handle to ensure that it cannot slip off during cleaning. The end result is a cleaning swab that is easier to use and more efficient at cleaning away persistent marks from the sensor.
