I just removed my stock seat covers cause they smell like mold.
I'm wondering if they're washable and if I can put them in the dryer?
Thanks for the help.

 

I'd put them on gentle wash (warm water), and then gentle/air dry (or if it's hot out, hang them outside).

 

I put them on warm-cold wash.
I let them air dry. It took off 98% of the mold and all the stains on them.
And, they smell really really good now.

Now, I'm taking the mold/mildew off the form.

 

The seatbacks with the zipper fit in the washer and dryer much better than the later ones that have the plastic clip thingy. So if you've got the plastic, kinda keep an eye on them in there.

And yeah, definitely don't wanna shrink them in the dryer. I tossed them in there for a very short time to remove the heavy water and for a little fluff and 'april freshness.' But then I hung them up to finish drying. A hanger hook fits nicely through the headrest hole.

Edit: and while I was typing, you were posting that you'd already done it, lol. Really cleans 'em up, huh? I did this with some out of a junkyard car, really dirty, too, and it got 'em like new!
