This double layer high absorbency fabric is super soft & made from super thin fibres. It is used in cleaning delicate surfaces such as space telescopes. The fabric is woven to be non-shedding. Its high absorbency capacity makes it absolutely ideal for sensor cleaning. The fabric has also a unique folding design that creates a softer edge compared to a hot sealing process. Compatible with VDust Plus & Smear Away. The specially developed mini-channel design provides an even saturation of the paddles surface while preventing pooling & vertical flow at the edge. This reduces streaks associated with traditional flat surface paddles. The mini-channels also provide the extra reservoir to absorb the excessive liquid & prolonging the moisture life of the swab during the cleaning process. 12 per pack.
