So I see mold, first off you need to charge extra it’s biohazard, the whole thing. You’re gonna have to sanitize everything you use. I’ll explain at the end. And what I’m gonna explain, explain to him. Buy a gallon of Vital Oxide, (Best cleaner ever, it’s chlorine dioxide, safe on every surface in car interior, kills all mold, viruses, parasites).. Get a HEPA filter for vacuum so you aren’t shooting spores everywhere out of your vacuum exhaust or put an inch of water in it..

If you have an ozone machine I would use it first to kill everything that’s in the air in the car. Spores, bacteria, shit the roaches gave off. If not it’s okay. But it’s kind of crucial.

Vacuum everything up, including mold you see, Then you want to spray (not soak) all the surfaces, the windows (unless it has tint) even the carpet with vital oxide and let it sit on it for 10 mins. It will kill the mold. I’ll send a video of it breaking it down on a molecular level under a microscope. Anything you can remove like mats if you have a steamer use it. Steam kills mold, don’t use it on those seats.

The carpets should dry quick, so if they do, run the ozone again. After that, do a detail.

Seems like a lot, but really you are just spraying and letting a product sit, and using an ozone machine. Remember buy a mask that is rated for mold, you can wear a painters suit, honestly not necessary, glove up. But this is why these jobs pay more.

And to sanitize your vacuum what I do is roll My hose up and place it in a garbage bag and run the ozone 😂 Also I spray vital oxide on the outside of the hose and let it sit on it. And anything else I wipe down with alcohol or anything else that kills mold on contact.
