Bad MLV has ruined interior

First post here, but have been lurking for a while


 


Here's my problem - A little over a year ago I decided to sound proof my Nissan Titan Crew Cab.  I bought some Butyl Fat Mat, CCF (neoprene), and some MLV off of ebay.


I saved quite a bit of money buying the MLV off ebay from a seller that I had seen on a few forums selling the stuff.


 


Turns out the MLV was bad...as in off-gassing like you wouldn't believe.  I had to MLV in my truck for 6-8 months, believing that it would finish off-gassing and be fine.  It never did.  Smelled as bad as it did brand new.  Ebay seller was aware, but was no help.


 


Now here I am, with a new truck that smells like some sort of weird plastic/chemical experiment.  This is even after I have removed everything, except for the couple of CDL tiles I have on the panels (which were not physically touching the MLV).  


 


I thought it would be fine after removing the bad MLV, but it still smells.  So I pulled out the carpet, tore off the jute backing (which was touching the MLV), pressure washed the carpet, and installed new jute on it. The back wall carpet got the same treatment. 


 The smell seemed to go away for a while, but now is still lingering.  It is probably at 20% of what it used to be, problem is that 20% is still enough to make my clothes smell after driving.


 


So I bought an Ozone machine -  A New Comfort HE-500 (supposed 3500 mg).  I have used it 3 times (30 min, 45 min, 1 hour about a month apart each time) and it seems to help for a few days, then the smell returns.  I have used einzette in the A/C system (which lingered for a long time).  The A/C doesnt have a noticeable smell, but will leave clothes smelly. Cabin filter has been changed mutliple times.  The steering wheel seems to have picked up an odd smell also. Interior is leather.


 


Febreeze, Ozium, Meguiars Odor eliminator, etc.  Nothing seems to kill this smell.  Leaving vinegar in the car helps, but the smell returns.  Air fresheners seem to just add to the scent.


 


I live in West Texas, so temps are over 100*. Smell is much worse in the heat.  I have left the windows down/cracked for a week at a time.


 


So I am not sure what to do at this point.  Have someone steam clean? Ozone for longer?  What chemical am I up against? Something that a fogger will work better on?

Try replacing your cabin filter and then running your air conditioning while you are using your ozone unit.


 


If that won't do it then you might want to try Biocide Auto Shocker or Dakota Odor Bomb, while your air conditioning is running.


 


Good Luck!
 
When I ran the ozone machine, I would run the air for 15 min or so during the treatment.  


 


Will the Biocide or Dakota bomb leave any residue or lingering smell?  I am afraid of putting so many chemicals on top of what is there and creating an even worse problem.
 
Mass Loaded Vinyl - apparently they use some sort of plasticizer in it to keep it flexible.
