Put some ice cubes in a zip-lock sandwich bag. Rub the bag of ice cubes over the upholstery until the candle wax freezes.
Scrape off the frozen wax particles with a butter knife. Pry off as much wax as possible.
Inspect the upholstery for any lingering wax residue or oily stains. If the upholstery is still stained, pour a dime-sized dollop of dry-cleaning solvent onto a dye-free rag.
Dab the remaining wax residue or oily spot with the rag until the residue or spot disappears. Fold the rag over once any wax or oil transfers onto it.
Blot the upholstery with a clean, dry rag to absorb any excess dry-cleaning solvent. Do not rinse the upholstery.
