Candle wax is usually oil-based, meaning water will have little to no effect – even when it is boiling. Instead, opt for a solvent that dissolves oil to help break down the spilled wax and lift it from whatever surface it is covering – just make sure to test the solvent on an inconspicuous spot first to ensure it doesn't stain the material. Krud Kutter, at Walmart, is able to cut through grease, oil and wax so it's handy to have in your cleaning collection.
