How to Remove Candle Ashes or Fireplace Soot
On table linens: Hold the fabric taut and use the vacuum's hose attachment to remove as much soot as possible. Sprinkle baking soda on the stain to absorb it. Let stand for 10 to 15 minutes, then vacuum again. Apply Tide Boost Pre-Treat Spray and wash in the warmest water safe for the fabric.
On the rug: Vacuum with the hose attachment. Then, for a wool rug, blot with WoolClean Dry Spot Remover No. 2, using a clean cloth. For a synthetic rug, apply diluted dish soap. If that doesn't do the trick, blot with Goof Off, followed by diluted dish soap. Wait 3 minutes, then rinse by dabbing on hot water. Blot dry.
