W4009C is a lightweight straight-texture polyester wipe in the sub-microfiber range. It provides a close fabric face for LCD-related work, assembly fixtures and contamination-sensitive surface-cleaning trials.
Make a light wipe work consistently
A light cloth is easy to handle, but too much cleaning liquid can cause it to bunch or leave a wet trail. For W4009C, set the wetting amount and folding method together so the working face remains controllable throughout the pass.
On small display-related parts, separate loose-particle removal from the final wet clean. This reduces the chance of dragging hard debris across the finish.
Match the report to the process risk
- Ionic contamination
- Request the ions measured, extraction conditions and applicable limits.
- Halogen-related requirements
- Define the substance limits relevant to the purchasing specification.
- Finished cleanliness
- Confirm that the evidence describes the selected washed and cut product.
These documents answer different questions and should not be treated as interchangeable cleanliness certificates.
Use the approved sheet count and washing option on the order so operators receive a consistent dispensing format.
