Combine the white vinegar, laundry detergent and 1 qt. warm distilled water in a bucket. Mixture should be in equal parts and small amount of detergent.
Dip a rag into the mixture, and "very gently" wipe down the faux leather item. Let mixture sit for several minutes.
Empty the bucket, and rinse it and the rag well. Add clean water to the bucket.
Dip the clean rag into the water, and wipe down the faux leather again to remove any residue.
Dry the faux leather gently with a soft rag.
Allow it to air dry outside long as possible, but not in direct sunlight.
*** This may be the best solution ***
Let the powder sit for an hour or two, or even overnight and vacuum it up afterwards.
Wiping the baking soda away with a damp cloth is another option if you don't want to drag out the vacuum cleaner.
