I have a couple stains on my headliner.

What do you guys use to clean it without damaging the headliner?

 

A damp microfiber cloth. Try just soapy water on the cloth first and if that doesn't work then get an all-purpose cleaner to spray on the cloth. DO NOT saturate the headliner and DO NOT use any kind of brush to scrub.

 

Headliner- if there are areas where your head touches the ceiling you will probably notice that these areas accumulate dirt and the like because of the oils that come from your hair and your skin that are now on the headliner.

Vacuum the headliner making sure you apply pressure, but not too much. Not only can you set the stains in this way, you may tear what can be very fragile upholstery if you press too hard. Vacuum thoroughly to make sure that you get all of the loose dust fragments

Cleaning - Duragloss 451 Fabric & Carpet Cleaner Aerosol Foam (FC) is a blend of surfactants, which gently foam away soil, oil and grease from fabric and carpet surfaces.

Spot cleaning can be done without leaving rings on fabrics, carpet and velour. Use Dr Joe dedicated Lint-Free 100% Cotton Blue Huck Surgical Towels, using very light pressure and wipe the headliner following the cleaning with the water based cleaner (do not soak or use hot water on the headliner fabric as it may delaminate) Dry by blotting with a clean, dry surgical huck towel

 

Folex, and a microfiber.
