Can you use Essential Oils with Dishwashing Tablets?Updated 18 hours ago

TL;DR: You can add a light fragrance to a dishwasher cycle, place 1-2 drops of an essential oil on top of a dishwasher tablet (do not pour oil into the dispenser), close the compartment and run the cycle. 🌿


How to do it (quick)

  1. Load your dishwasher as normal and place the tablet in the detergent compartment.
  2. Add 1-2 drops of your chosen Koh essential oil directly onto the top surface of the tablet.
  3. Close the tablet compartment as normal. Do not pour oil into the dispenser or directly into the machine.
  4. Run the cycle. Enjoy a subtle scent. Avoid overdoing it (more drops = stronger residue risk).

Safety & best practice

  • Start small: use 1-2 drops and try one cycle first to check for any smell or residue you don’t like.
  • Don’t pour oil into the dispenser, spray arms, or directly onto plastic seals. Oils are concentrated - poured straight in they can leave residue or affect machine parts over time.
  • Avoid heavy use: frequent large doses could leave residue on glasses or cutlery; if that happens, reduce the drops or stop using oils.
  • Test fragile items: if washing delicate glassware or porous items, consider removing them for the scented cycle or skip oils that day.
  • Keep oils away from children & pets and store them safely.

Will it affect cleaning?

Used sparingly (1-2 drops) the oil should not affect detergency for most loads. If you notice visible residue or scents you don’t like, reduce the amount or stop using oils.
