With my recent purchase of a 2014 GX I've been spending some time cleaning it up a bit. What do you guys use to clean the headliner? I'm asking because I am wary of doing something wrong and having the glue separate and have a saggy headliner. It's not dirty by any means, i'm more interested in things that can clean out any lingering odor.

Any tips or product advice would help a lot. thanks.

 

scrubbing bubbles work wonder to clean upholstery and headliner.

I was able to clean an area around driver area with just a Costco micro-fiber towel and water on mine. Headliner was basically spotless elsewhere but I could see some stains in the right light that appeared to be a latte gone astray by previous owner.
