Would this work well to remove the smell of forest fire smoke from synthetic sleeping bags?

Yes. I used it for my coat and sleeping bag after working a backcountry trail crew all summer. Removed the stains and most of the smells. I used a little bit of white vinegar for the rest.

How long does the product itself last? Is it shelf stable for a few years? Or does it degrade and not clean well after being opened for a year?

it is shelf stable for a year . I have used it after its been open for a while and it cleans just as well.

Does this product contain UV brightners?

Definitely NOT! There is a potential for problems if you wear clothes impregnated with optical brighteners in natural sunlight. You should definitely avoid UV brighteners. NikWax is the best product that you can use for your outdoor wear. It will keep your active wear looking and performing like new. No, I don't work for NikWax:} I'm a skier with a lot of pants and jackets. Kjus, a manufacturer of luxury ski wear, actually recommends NikWax on their site for care. I've been using NikWax products for years and it has kept everything perfect and won't strip the clothing of its protective coating. I use more than just the Techwash too. I use their down wash product and also some of their leather waterproofing and cleaning products on my gloves and footwear.

Would this be a good choice for getting the smell of forest fire smoke out of synthetic sleeping bags?

I thank it will work. Used it to clean motorcycle riding gear and it gave good results.
