Headliner cleaning
Headliner cleaning is the careful process of cleaning the fabric or perforated material lining the inside of a car's roof.
What it means
The headliner is the fabric or synthetic surface attached to the inside of the roof. It is typically a thin fabric or perforated material bonded to a foam backing that is itself glued to a board. The whole assembly is delicate. Aggressive cleaning, scrubbing, or over-wetting can dissolve the glue between the fabric and the foam, causing the headliner to sag visibly within weeks. Yet the headliner does get dirty: cigarette smoke (in older second-hand cars), greasy fingerprints near sunroofs, and slow general dust loading all show up over time. Cleaning the headliner safely uses minimal moisture: a microfibre dampened (not wet) with a mild interior cleaner is dabbed and wiped lightly across the surface in straight strokes. Stubborn marks may need a second pass after a brief drying interval. Headliners are one of the few interior surfaces where less-is-more is the only safe approach. Professional headliner repair (re-glueing a sagging headliner, or replacing the entire assembly) is a separate, more involved job.
Why it matters in Singapore
Singapore's heat speeds up the breakdown of headliner adhesives over years. Older cars often start sagging at the rear corners or near the rear windscreen first. Cleaning the headliner correctly, without contributing to glue breakdown, becomes more important on cars approaching their second half of the COE term.
