Dry cleaning for tweed jacket?

[Spartan Tartan]

Is it a "slight" smell or a strong smell?

If it's slight, you might have better luck. In this case I would imagine dry cleaning would work. I also leave my hanging out in the open (i.e. NOT in my closet) after I wear them so they can breath a bit. I'm not sure it's necessary, but it's what I do.

If the odor is strong enough to really bother you, then you have nothing to loose if you try.

But to the point of your question... is dry cleaning safe for your tweed jacket. I would think yes. I've dry cleaned all of mine without issue.

Best of luck!
