Like the cleanrooms themselves, cleanroom wipes have different classifications to be used in corresponding cleanrooms. For instance, many cleanroom wipes are compatible with ISO class 6 or higher. Likewise, the wipes are also produced in cleanroom environments, to ensure the highest possible quality.
The difference between a normal cleaning cloth and a cleanroom cleaning wipe is how much lint or particles come off the wipe. Cleanroom wipes are very low-linting or non-linting depending on the material. Nonwoven lint-free cleanroom wipes are the most popular and are often called lint-free paper towels. They are considered low-linting since they are made of cellulose, which is not truly lint-free. Pre-laundered polyester cleanroom cleaning wipes are the cleanest available. They have been washed in purified filtered water before being packaged to ensure any loose particles are removed from the wipe. They are then dried and packaged inside of a clean room.
