  • Shake often – While infusing, to allow best extraction of oils
  • Use cheesecloth – To get a smooth liquid without gritty grounds
  • Work in sections – Apply polish in small areas to avoid it drying out
  • Buff to shine – With a clean, dry cloth after polishing

Storage and Shelf Life

This furniture polish should be stored in an airtight container out of direct sunlight. The vinegar acts as a natural preservative to prevent bacteria growth. Properly stored, the polish will keep for 2-3 months.

Over time, the grounds will continue to infuse, making the mixture stronger. If it becomes too strong, you can dilute it with more oil and vinegar.

When it starts to smell rancid or you see mold, it’s time to discard and make a fresh batch.
