The micro Absorbond swab is an excellent swab for cleaning very small grooved, slotted and recessed areas. The softness of the Absorbond head also makes it a good choice for sensitive surfaces and cleaning delicate optical components including coated lenses, fiber-optic sensors, and mirrors. - The hydroentangled nonwoven polyester micro tip is extremely low in nonvolatile residue. Double-layered material provides enhanced softness and absorbency. Excellent chemical resistance.
