About Circum Wash
Circum Wash is a trading name used by Circumtec Pty Ltd, an Australian-owned payments company based in Cheltenham, Victoria. Circumtec supplies cashless payment hardware, software and support for self‑service car washes, vacuums, dog washes, vending machines and laundromats across Australia. Their Circum Pay app and tap‑and‑go terminals let you start and control a wash using a credit/debit card or mobile wallet instead of coins, while Circumtec processes the card transaction on behalf of the local car wash operator.
A Circum Wash or Circumtec Mentone charge typically appears when you tap your card or phone at a self‑service car wash bay, automatic car wash, vacuum, fragrance machine or related equipment fitted with Circumtec’s reader. For self‑serve bays, the system uses an incremental pricing model: your bank first places a temporary pre‑authorisation of around AU$15, with an initial AU$5 minimum spend loaded to the bay; as your remaining time drops, additional AU$1 increments may be added until you press stop, and only the actual amount of time used is finally debited. The pre‑authorised amount itself is a pending hold, not a completed sale, and your bank normally releases any unused portion within 24–48 hours.
If you’re unsure about a Circum Wash or Circumtec Mentone charge, start by thinking back to any recent self‑service car wash, dog wash, laundromat or vending machine you used in Australia, and check whether anyone else on your account may have used their card there. You can then visit circumtec.com.au and use the “Find My Receipt” tool to look up a detailed receipt by date, amount and card details, or contact Circumtec’s support team via their contact form or by calling 1300 656 882 for clarification. If you believe you’ve been overcharged or billed in error, Circumtec can investigate the specific transaction, explain pre‑authorisation holds and, where appropriate, work with the wash operator and your bank to correct or refund the charge.
