The visible dust ez sensor cleaning kit plus includes 1.15ml of vdust plus fluid, a sensor cleaning brush and 5 orange 1.0x 24mm dhap super soft fabric sensor cleaning swabs. If you are unsure as to the nature of your stain or you get both water and lubricant stains, vdust plus will fit the bill perfectly. Designed to clean away water and most oil stains, vdust plus eliminates streaking and provides a moderate static barrier. The orange swabs' double layer high absorbency fabric is super soft, made of super thin fibres and is woven to be non shedding. Its high absorbency capacity makes it ideal for the surface cleaning of delicate optics it is used in cleaning space telescopes! The fabric has also a unique folding design that creates a softer edge compared to a hot sealing process. The specially developed mini channel design provides an even saturation of the paddles surface while preventing pooling and vertical flow at the edge, reducing streaks associated with traditional flat surface paddles.
