How to remove mold and mildew from inside of a car that been parked

what type of upholstery ...and how much mold.....and how much rust

You need a professional to rid the car of mold and mildew, even then you might not get a guarantee. I'd call a body shop that does repair on cars that have been in accidents. They could probably give you some names of a local business, to clean the car. Get it in writing, just what will be done, how long will it take, how much, and is there a guarantee. Good Luck!

Let the Air Get to it.........

Don't know if this will help but here is my story...Rainy season in FL, left windows of the car open. Nasty. Smelled like old man stinky feet death... gross. I let car air out to dry out, when almost dry I flooded the car with vinegar and rolled up the windows. Darn thing steamed up like two teenagers at a drive-in movie. When steam left, I opened the windows again to let the car dry out and air out. Was getting rides with others while this was doing 'its thing'. In a few days, interior was dry and had no smell what so ever. This is not the end of the story...It happened again, stupid me. This time the car really flooded inside with the cup holders full of water. Did the same thing. Car was perfect. Drove that poor thing for another two years until I sold it, and they never had any smelly trouble from it. My suggestion would be to wipe or vacuum any surface mold, then hit that sucker with as much vinegar as you can buy (stuff is cheap). Good Luck!

Let the air get to it. Also when you have to shut it up place activated charcoal in a dish inside. It's great to absorb odors. You could also try a dish with baking soda. I had a used car that I picked up from the owner on a rainy day-smelled like wet dog. Shampooed the carpeting which helped.

With mold, always add a few drops of clove oil to your cleaning rag/liquid. Clove oil kills the mold spores so they don't come again. Many people use bleach, but that just wipes off the appearance of the mold, but doesn't kill the spores. Yeah CLOVE OIL !!

White vinegar works like the reply from Tammy Hawkins suggests. Something else to use is a spray bottle of peroxide Spray the mold instead of wiping and let dry, the peroxide will kill any mold until dry, all natural no odors.

hit it with a good leather cleaner...one made for saddles. Often the mold is on the surface. The other area clean as if it's your house...vinager, commercial product. If lots of mold and spores wear mask.

Saddle soap. A good scrub down. Then milk oil to keep it soft. Often the mold isn't in the leather but surface only. Well, thats true for saddles. My cousins woul go to auction and buy saddles and saddle parts....then repair and scrub clean.

We sprayed the inside of my client's car with white vinegar, opened the windows and aired it out. Took a couple days of spraying lightly but it went away.

Ah, the above was on car seats that were upholstered.

Call your insurance agent! We lived in Houston, I was gone for a month, my car was parked with front windshield screen up and my husband used his car. Finally, I was coming home and my husband went out to get my car ready for me to start using when I got home. He opened the car door and the inside of the car was covered in mushrooms! There had been a small leak around the front windshield that we did not know about. Car was totaled.
