The headliner cloth in my 'bird is sagging, and near the t-tops, the fiberglass is exposed. In the exposed areas, there is some very dark discoloration in spots that looks like mold or mildew, but I'm not 100% sure. I'd like to repair the headliner using the steps in the technical article on this site instead of buying a new one, but I worry that driving the car with black mold still in there is probably not the best thing for my health. Has anyone else had this problem? How can I be sure the mold is dead--what chemicals can I use without destroying the fiberglass or ruining my chances of repairing it?

I've been told tea tree oil works well for kill all types of mold. Once the mold is dead, then steam clean or similar to get rid of the stains.

I did a quick google and got this;

don't forget to fix the leak in the t-tops to this doesn't reoccur.

good luck!

Mold is a fungus that few kind chemicals can treat or kill without some effect or damage to the treated surface or to yourself. You might try an on-line search on the mold topic then pick up whatever you can at the home improvement store for a do-it yourself treatment job and hope for the best but, chances are there will be some staining and or you may ruin the cardboard backing anyway...or stain fabric facing.

Give it a try, and good luck

Thanks, I'll try it.

> don't forget to fix the leak in the t-tops to this doesn't reoccur.

It was raining pretty hard last night and I spent some time in the car and I didn't see any leaks. I think the previous owner may have left it in the rain without the tops on or something.

My intention is to replace the fabric anyway; my main concern is that I'd just be covering up a potential health hazard.
