Cleaning fake flowers/vines.
If you have fake flowers that are dusty you can put about 1/2 cup of salt in a bag that is big enough to fit the flowers down in blooms first. Best if you do this outside or over the bathtub. Grasp the bag tightly around the stems and shake it around for about a minute. Shake the flowers gently as you remove them from the bag so the salt from the flowers falls mostly in the bag. Check to see if they're dustless enough. If so shake and tap the stems to remove the rest of the salt. I've heard you can use cornmeal or baking soda as well. I've only ever done salt. Clean sand might work but that's kinda rare to have just lying around unless you have some left over from potting plants or something. You can remove some pretty heavy dust doing this but if the flowers have been wet or stained it doesn't work. Better quality flowers come out of this process a little better than those that are thin fabric with no edging on the petals. Sometimes those can fray a little at the edges. Its excellent for velvety finished flowers that you can't rub with a cloth. I've even cleaned decorated grapevine wreaths with salt in a box. It was really messy though. I didn't think to take it outside first and it would've helped if I had taped up the corners of the box before shaking it around. :p
