You can use several bleaches— common household bleach, full-strength ammonia or oxalic acid. They are all hazardous to some degree, so take precautions. Always wear rubber gloves, and always wear safety glasses. This may be a nuisance, but it makes very good sense. You could burn your skin or lose your eyesight if any of the bleach accidently splashes, and even experienced hands have accidental spills and splashes.
We don't recommend ammonia because its strong odor can overcome you. We do recommend a regular chlorinated household bleach. If that doesn't work, you can progress to oxalic acid, keeping in mind that it is strong and can do damage to both you and your furniture. Use it accordingly. Follow the instructions on the label to make the oxalic acid solution— and follow them exactly.
