The safest way to clean most headliner stains is to use a gentle, foam-based upholstery cleaner and a soft-bristled brush. The headliner is a delicate fabric glued to the roof, so the key is to avoid soaking it, which can cause the adhesive to fail and the headliner to sag. Always test any cleaner in an inconspicuous area first, like near the edge of a sun visor, to ensure it doesn't cause discoloration or damage.
Start by vacuuming the area to remove loose dirt and dust. For a DIY solution, mix a small amount of mild dish soap (like Dawn) with warm water. The goal is to create a light sudsy mixture, not a soapy water bath. Apply only the foam to a clean, white microfiber cloth—never spray directly onto the headliner. Gently dab and blot the stain, working from the outside inward to prevent it from spreading.
For tougher stains like grease or ink, a dedicated automotive interior cleaner is more effective. These are formulated to break down specific stains without harsh chemicals that can harm the fabric. After cleaning, use a separate damp microfiber cloth to rinse the area by blotting, and then a dry cloth to absorb as much moisture as possible. Allow the headliner to air dry completely with the windows cracked open.
