Baking Soda is a good refresher, too.

I also bought some charms from ebay and they smelled of smoke. I put them in a lingerie bag and put them in the washer on delicate rinse with cold water. Put some vinegar in the rinse and when they were done laid them out flat to dry. Had to press them but they didn't smell.

Put them in a baggie with some coffee grounds. The coffee grounds will absorb the odor. I bought a Featherweight that had a terrible stinky carrying case. A friend said to use coffee. I put a small topless container in the top and amazingly the musty smell is gone. I have left the container in the case and just put it aside when using the Featherweight.
The coffee also got sprinkled in the back of our car because someones cat got in there and did something that made the car unbearable to be in. It even took away that odor.
Believe an old wife anyday!!

dryer sheets in a sip lock works great

They say vinegar will eliminate the smell. Maybe close them up in a box with a dish of vinegar?

Febreeze works great!

a can of OUST .

My sympathy to you. Not a pleasant experience. I do wash small charms, new ones from the mfg. I prepare a basin of warm water, with lots of suds. I do all the light colored charms first. The charms are loosely arranged into the sudsy water, and I alternate soaking and then pat them, giving them and up and down motion. No wringing. Sometimes I let them sit for a day. Complete the rinsing the second day. Leaving them spread on a fluffy towel to dry. Second batch is for darker colors. Third batch is for reds. Beware the red dyes, even in quality fabrics!

Even smokers can smell the smoke in fabrics and houses. When I get things, I put them in a tub with a lid and put a couple of downy in them. takes the smell out. Maybe this thread will open eyes....non smoker or smoker. LOL But if the prices are good, I will wash large pieces or air out my charms.

Dial Gold soap. Open package wrap 1 sheet of tissue paper around, and place with charm squares inside a ziploc bag for 1 to 2 days. It works on big quilts also. It has to be the Dial Gold bar for some reason or other. We found this out at a quilt sale room where we were stuck in the corner with smoke smell quilts that someone had dropped off. When we opened the bag WOW. We put the soap in the bag,and by the next day you couldn't tell it anymore.
