"Old Car Smell"

[Dr_Snooz]

My car spent many years baking in the sun through the hottest part of every day in Fresno's hellfire summers. The paint is completely had, but the interior is in surprisingly good shape. The only problem is "old car smell." It's that distinct smell of old, deteriorating plastic. I've looked around on this site and the web for an answer. Most people say it's the carpet. I'm wondering if anyone here can confirm that before I spent a bundle on new carpet?

Thanks!

It's probably everything. My car had old car smell. I pressure washed the carpets, put in different seats, removed the back seats, repainted much of hte plastic and simple-greened EVERYTHING. And it still smells bad.

My old sei had old car smell, and wierd people smell when I bought it... leather doesnt absorb smells too badly though so after a good cleaning, and carpet cleaning it was ok. I removed my seats and vacuumed and scrubbed though as there was some funky shit in there.

New car has wierd ... I live by the ocean and wet smell. Not wet though, so I am thinking it is insulation and such and carpet maybe. Grey interior will be swapped in this weekend to hopefully get rid of that though.

Your best bet is to clean, clean, and clean some more. Use good products that have a nice scent lol. And if you can, try shampooing the seats... it's the fabrics/carpet in the car that will absorb most of the smells.

The carpets do hold a LOT of your odors. There's also some sound deadening behind the dash that gets funky after 20 years.

Anything porous will hold smells. Fabric, foam, carpet, hardboard (the door panels), and some of the soft plastics. Steam clean what you can.

Never thought of the sound deadening stuff behind the dash. I guess thats what causing the smell in my car. I've pretty much washed/cleaned up everything, seats, carpets, headliner and every plastic panel and it still smells.

I dunno but I think all old car smells the same lol. I wonder what caused it anyway?

I had a weird odor in my trunk before. I took the carpet out and scrubbed it with simple green and then pressure washed it. Tons of dirts came out. Since then my trunk smells great

let me clarify, old Japanese car smell. all of these toyotas, nissans, and Hondas have a distinctive odor, I think it is the polymer based materials (plastics in the door panel, headlliner , carpets..add mildew and you have it magnified.
You should shampoo the upholstery and carpet and get an ionizer ..deionizer whatever those are, they suck the smell out of anything if you let them run a couple of days. They really work good.

[Dr_Snooz]

Thanks guys. I did steam clean it and that helped a lot. I'll give it another go and try the ionizer too.

Funny, when I got my hatch and I got in I was thinking "ahh, the smell of an old Honda, I forgot that smell" hehe. I wouldn't go so far as to say it's pleasant or anything, but it doesn't bother me. My Peugeot 505 also had a unique odor, something like diesel + leather hehe.

carpet isn't expensive. go to autocarpetoriginals.com tell em tim yoak sent ya,i don't mind reccomending them because i've seen their stuff in person and it's excellent , and reasonable. plus the owner is a really nice guy. as soon as i get my tax money i will be ordering mine from there. i figure if someone has a good product for our cars at a reasonable price i don't mind mentioning it. as far as the old car smell, the carpet will kill the funky smell, theres a lot of heavy padding under it and it soaks up smell like crazy. a lot of it is mildew in the padding, if you go to a yard where the car has got wet the smell is much worse.

yeah i noticed that most of the junkyard car have that same nasty smell....i like to call it the junkyard smell.

Do I need to buy padding too or does that come with the carpet?

[Blkblurr]

Don't forget the headliner. Clean it too

I'm wondering about this padding too.

I noticed in my parts car that the "padded liner" if you will(against the firewall in the cabin), was damp when I was stripping everything down. I think probably once it gets wet at all the bacteria will start to molest it quite quickly, this would be a source of smell among the other things.

[Dr_Snooz]

Incidentally, I shot some Vinylex in the A/C vents and that killed the smell. For a while at least. It still comes back when the car sits in the sun.

[redaztec]

My carpet (from stockinteriors.com) came with the padding. It's been a while since I ripped the old carpet out, but I think that some of that old car/dirty car smell went away with the old carpet (which was absolutely filthy). More of the smell went away as I have cleaned more of the interior. Even after all that some "old Honda smell" still remains, but I don't really mind as long as it's clean!

[Dr_Snooz]

Thought I'd bring this one back from the dead. The car doesn't smell anymore and I don't know why. It smelled like decomposing plastic for as long as I've had it and then one day the windows turned cloudy and it stopped smelling.

My hypothesis is that using Zymol vinyl conditioner on the interior did it. Their marketing literature mentions something about the formulation helping to bring the destructive chemicals out of the plastic so it lasts longer. I know the Zymol makes the plastic look brand new, but now I suspect it brought out something foul that clouded the windows and made it stop smelling. I'm not sure if it will come back, but I'm pretty happy for now.

my wifes sentra was like that. if you're not super anal about cleaning, family cars do develop some "unique" smells

[2drSE-i]

I think you just got used to the smell

I get these air fresheners at Wal Mart in the area with the other air freshening stuff.

Unfortunately, the site is down right now so I can't post a link to the solid air freshener I am talking about, but if you try tomorrow maybe the site will be working.

I keep one under the passenger seat at all times. The "Pure Linen" scent is unobtrusive and nice. This freshener also has activated charcoal in it and they last a REALLY long time.

[lostforawhile]

I kind of really like the old car smell. if you want to kill a lot of it, get a 10 pound bag of charcoal cut it open longways, put it in the car with the windows closed for a couple of days. it will absorb everything. when you are done, have a cookout.

You raise a good point. It was after the latest steam clean of the interior that it stopped smelling. I got the seats, under the seats, the door panels and everything. Even the speaker covers. I think this is the first steam clean since I replaced the headliner, which was definitely decomposing. That could have been the source of the smell and the steam clean got the last of the residual smell.

I guess the moral of the story is that old car smell can come from any number of sources and you may never know what it was even if you get it. Nevertheless, you can get rid of it with thorough cleaning and brute persistence.

Not exactly the magic bullet I was looking for when I started this thread, but whatever.

(BTW: I don't use chemical fragrance of any kind. Chemical perfumes are great in theory but their persistent, neurological effects should give you pause.)
