my car got wet inside and sat like that a few days over the spring.
I noticed a musty smell inside that wasn't normally there. I left it out in the sun a few days to dry it out, but am concerned something might have taken a foot hold.
everything I found seems to be stuff you soak things in to kill it off, but hoping I just couldn't find it and someone has a good one to use on a car, not like a basement wall.

I have used a 50/50 mixture of warm water and white vinegar applied with a damp washcloth with good results.

Ammonia kills the mold and mildew and is odourless once its dry. My car literally had every surface covered in mold and mildew. washed it with straight ammonia - all gone !!

I don't physically see any.
I was thinking of like the door backing, carpet, and headliner type stuff.
I think we have all pulled water damaged door panels, and I was thinking there might be stuff behind it.
but if the only way is to wipe ever surface instead of spraying, then I might just have to wait till it is a bit cooler and poke around.

Ammonia will still work.
Pour some into a cup set it anywhere. Close the doors and windows and let it sit for a few hours.
Anymore I just open the lid on the bottle and not bother with pouring any out.
It will clear the smell of corned beef and cabbage from the entire house. It works that good.

lol, ok, I will give that a try.

Corned beef & cabbage ain't nothin' - try boiled turnips !
That'll drive you out of the house...

can you put in a spray bottle and gently spray like under the seats and other hard to get to places?

Corned beef and cabbage, one of my brother favorites but you didn't want to be around him the next day 💨💩💨. We were Christmas shopping one year in a JC Penneys. He grabs me and says c'mon lets go, I'm like what's the hurry
he goes over across the main aisle from where we were and starts looking at Christmas cards he says just watch,
As the people walked into his Napalm they'd start looking around😳, up at the ceiling vents🙄 and start moving real fast. That was over 40 years ago and i still split a gut laughing about it. just did again 🤣🤣🤣🤣
