Microfiber cleaning cloths trap dirt and bacteria through a combination of their unique material structure and electrostatic properties. Here's how they work:
Microfiber Structure
Tiny Fibers: Microfiber is made from extremely fine synthetic fibers (usually a blend of polyester and polyamide) that are much thinner than human hair. These fibers are split into even finer strands, creating a large surface area for capturing particles.
Split Fibers: Each fiber is split into many smaller segments, creating tiny hooks and crevices. These hooks grab onto dirt, dust, oils, and bacteria, pulling them into the cloth rather than just pushing them around like traditional fabrics.
Electrostatic Attraction
Static Charge: Microfiber cloths generate a small electrostatic charge as they move across surfaces. This charge helps attract dust, dirt, and other particles, especially those that are too small to be seen by the naked eye.
Trapping Particles: The charged fibers hold onto these particles until the cloth is washed, preventing them from being released back into the air or onto the surface being cleaned.

Capillary Action
Absorption of Liquids: Microfiber cloths can absorb liquids, oils, and grease effectively due to capillary action. The fibers wick up moisture and oils, trapping them within the cloth.
Bacteria Capture: Microfiber’s ability to trap not only dirt but also bacteria is enhanced by its tiny fibers, which are small enough to capture microbes. Studies have shown that microfiber cloths can remove up to 99% of bacteria from surfaces when used properly.
No Chemical Dependency
Mechanical Cleaning: The physical structure of microfiber allows it to clean surfaces and trap bacteria without needing chemicals or cleaning agents. However, if disinfecting is required, microfiber cloths can still be used in combination with cleaning solutions to enhance their effectiveness.
The fine structure, electrostatic properties, and high absorption capabilities of microfiber cloths make them highly effective at trapping dirt, dust, oils, and bacteria.
