There is a long line of what appears to be a water stain on the roof of my '03 supercrew. My mother left the sunroof open one night and i believe it rained. I've tried scrubbing it with soap and water but the line just returns once i think it's gone.

The best way to describe it without pictures is that it looks like the sweat stain on the brim of a baseball hat after it has dried.

Please.

Try clay.

 

Question, is this on the inside, or the outside? First time I read your post, I thought the outside, on the paint. But then, reading again, it seems it's on the inside fabric?

I'm leaning more towards the interior (based on the sweat stain comment).

If on the inside, whatever you go with, remember that it will likely soak through to the adhesive that is behind and holding the headliner material to the substrate. As such, you don't want to use anything that is going to zap the adhesive and cause a sag.

I'm pretty adverse to working on a headliner other than on tiny spots (like a spalash from opening a Coke can) so, I'm not exactly comfortable advising on what chems that you should or shouldn't give a whirl.

If it were mine - and this is a USE IT AT YOUR OWN RISK piece of advice -

I would first try a VERY dilute solution of APC+ and water. Again, very dilute. That headliner material is the thickness of a piece of paper and will soak EVERYTHING up. I would VERY lightly blot the stain with a 100% cotton terry towel and then allow it to dry. I'd then repeat if needed.

I wouldn't get in a hurry. Be ultra patient.

I'd be hesitant to go after it with any type of fabric cleaner as they will contain serious surfactants and, likely, some level of a degreaser (solvent). My personal opinion is that this type of a product will chew on the adhesive and could cause a serious sag down the road.

 

Thanks for that, and yes.. It's on the inside in the headliner. I'm going to try a terry cloth with just water today when i get home from school. If that dosn't do it i will try like you said a verrry dilute solution.

I'll snap some pictures of the stain today after school and work when i get a chance.

 

That's what i'm referring to.
