Katrina-resurrected Porsche: how to rid of mold on leather...
Helping a 928-er restore a car rescued from Katrina: mold and spiders throughout: see the pics.
Some of the leather is not shrunken to the point of needing replacement on that aspect alone, though still has mold and discoloration. There are also mis-matching pieces inside that would need restaining at a minimum. My thought: find a way to remove the mold and dress the leather, possibly re-stain it via Leatherique or such, and replace the torn/stretched leather with new but it too would need to be stained to match the existing. Thoughts?? Mark

One must ask this question.
Why?

part it out. buy one just like it. it will be cheaper, i am betting.
it think to truly rid the car of mold, you are going to have to strip the interior down to the metal, clean really really really good, then replace the entire interior with new. IMO, etc.

My opinion is that you'll never get the leather, vinyl, or carpet clean. Without gutting the car you'll never get the underlying sheetmetal clean either, not to mention the electrical contacts with corrosion that should be attended to, ECUs that need replaced, seat motors, instruments, etc. Were it me I would gut the entire interior and throw it in the dumpster, then find a good donor 928 and use the interior. The upside is that it is relatively easy to find a 928 parts car.

As has been stated this is a project from hell, literally. The interior will be one of the easy parts of this ordeal. If the owner has the patients and budget it can be done. Hope the intended recipients are still very young.
The electronics on this model will be a major task, followed by the mechanicals. this will need a complete disassembly, be very careful when removing the wiring harness, DO NOT CUT. Hope no aftermarket electrics were added, alarm sound system, etc; as these can cause problems for cars that did not get wet. The body will need to be taken to bare metal, it should be dipped to get to all hidden inter-panel spaces. Rust repair as needed. All new body seals. Back to the original question, the interior, it would be better to just throw out everything and start over with new materials or source a parts car. A parts cars could also help with other areas. An ambitious project, best of luck with it if you go forward. |

Irrational and unwise to restore unless you strip it to the bare chassis removing all interior, wiring, suspension, mechanical and then rebuild using a clean donor car that has it all. This would be to maintain the "original car" the vin# in other words. You would still be dealing with a body shell subjected to terminal salt soaking that will most likely surface as major rust at some point. Therefore it would be crazy to take this kind of project on due to the absurd amount of labor and money needed to complete it in relation to it's low market value. Sadly you must ignore the sentimental value in this case. You could always salvage a few parts such as the hood crest, steering wheel, wheels?? as "original parts" to add to the new car you find.
Find an identical car and fuggadaboutit |

It wasn't under water & there doesn't appear to be much corrosion inside the car, yet still the mold remains. I've already rebuilt his engine: interior is next on his list.
I might be better off sourcing a used, complete interior as he's already committed to going that far. :/ Mark

I take that back: who knows, it may have been under-water but there's no evidence inside the car except all the mold.

Why is the headliner moldy and discolored if the car wasn't under water?

Keep in mind that mold can be toxic and can't be removed from the interior....
it will always be there unless you replace the interior entirely but that wont address the electrical issues, mechanical issues, and rust issues that car is sure to have or develop. |

You didn't say how high up the water came. Most of these comments seem to assume the entire car was submerged.
That mold could grow just from having wet carpets and having the car closed up for a long time, but if the water didn't come up any higher than the bottom of the seats, it might not be a huge deal. Edit... I was typing kinda slow... looks like my questions have been answered.

OK you rebuilt the engine, good. How about the gearbox and the rest of the drive-line?
Just keep in mind the electrics are the most troublesome area for these cars, and those are the ones that have not been wet. |

2 gallons of water in a foot well with windows up for a period of time will destroy electrical under dash and instrument panel etc. due to high humidity and condensation not to mention the moldy interior. That alone would be enough to kill a 928 if the rest of it isn't mint. The biggest reason 928s suffer from failures is due to electrical gremlins, anyone ever seen the factory relay box in one of those???. Good lord, what a debacle. The distorted door panels should be a dead give away this car saw serious water as in at least higher than the door bottoms.
For reference to overall value- 1978 928 porsche If anyone wants to see what a factory fuse/relay panel looks like in a 928 then here you go- if it weren't for this I would pick a 928 up for kicks. Troubleshooting my fuse box 1986 928S - YouTube |

Imagine chasing electrical gremlins in this after it got wet with salt water.....
 this is a factory original part |

Ah, manual gearbox. The 928 guys like these. That should pay for the car.
The rest, umm two tons of scrap metal at today prices... |

Lysol Concentrate will remove that, but the smell will be with the car for a while, and the stuff is classified as a pesticide. You would also have to spot test it, and then you would need to condition the leather. Swapping interiors is the better idea.
One fellow on the other site did rescue a 928 from Katrina, but he stripped the car while it was still wet and dried the leather off of the seats and then reinstalled everything. Also, heat kills mold. They do this in house remediation, and it would probably not be so tough to heat up a car. Then you could use any type of cleaning products to remove the residue. |
