The headliner in most modern vehicles is typically made of a material called tricot. Tricot is a type of knit fabric that is durable, flexible, and provides a smooth surface for the headliner. It is often backed with foam or other padding to provide insulation and sound dampening. This material is chosen for its ability to maintain its shape and appearance over time, as well as its ease of installation during the vehicle manufacturing process. **

To clean stains on the car headliner, start by gently vacuuming the area to remove any loose dirt or debris. Then, mix a small amount of mild detergent with water and use a soft-bristled brush to gently scrub the stained area. Be careful not to oversaturate the headliner, as excessive moisture can cause damage. After scrubbing, use a clean, damp cloth to wipe away the detergent and then allow the headliner to air dry. If the stain persists, you may need to use a specialized automotive upholstery cleaner, following the manufacturer's instructions carefully. **
