Let the wax solidify before attempting to remove it. Wax becomes more brittle and easier to take off when it’s cold. Therefore, consider placing the linens in the freezer or use an ice cube wrapped in a plastic bag. After the wax has hardened, carefully scrape it off with a dull butter knife, making sure not to harm the fabric by avoiding any vigorous scraping. Colored candles often leave stains because of their dyes; if you see an oily residue, it may be best to have the item professionally dry-cleaned.
