You will want to allow the wax to harden before you attempt to remove it. When wax is frozen, it becomes even more brittle and is easier to remove, so either place the linens in the freezer or rub with an ice cube wrapped in a plastic sandwich bag. Once the wax is hard, gently flake it off with a dull butter knife. Do not scrape since this may damage the fibers. The dyes used in colored candles may leave behind stain; if an oily spot remains, have the item dry cleaned.
