4009K is a thin, straight-texture sub-microfiber wipe for controlled contact on small parts and LCD-related fixtures. Its polyester construction offers a close working face with several finished-edge choices.
A thin working face for restricted access
When a folded cloth must fit between adjacent fixtures, extra bulk can prevent even contact. The listed thin construction of 4009K makes it a candidate for trials where operators need a compact fold or a wipe held against a small support.
Do not force the cloth into a gap where the sealed rim catches on an edge. Select an appropriate sheet format and confirm that the holder or fold presents fabric evenly to the work.
Flat parts
Use short, repeatable passes and inspect after drying. A light touch with a fresh face is often more controllable than repeated scrubbing with the same contaminated area.
Fixtures and supports
Clean the contact support as well as the workpiece. Residue on a support can transfer back onto a surface immediately after it has been wiped.
For a sensitive assembly process, specify the finished-wipe particle test and cleanliness documentation required for acceptance. Keep the selected wash and pack format in the purchasing record.
