This is an excellent benchtop wipe sized for the rework bench, and a perennial MicroCare best-seller. Polyester and cellulose fabric. Economically priced, convenient package size. Medium absorption, medium weight, relatively lint-free, good purity. While it's the optimal size for use on the rework bench, it's probably too small for stencil cleaning. Smooth, white, medium absorbency, standard packaging. The "W66CP" part number is the exact same wipe in a jumbo-sized, economy package. Save about 30% per wipe with the economy packaging.
