Set the timer to 21 seconds

Online timer for 21 seconds

While disinfecting your footwear before visiting a pest-free island, stand still and let the solution remain on the soles for 21 seconds. The brief pause keeps you from stepping away too soon while dirt, seeds, or other material may still be lodged in the tread. At a New Zealand departure point, use the moment to watch the countdown rather than touching another surface.

As you wait beside the cleaning station, sound may quietly switch to connected earphones. A timer that appears silent can still be running, so keep the screen visible instead of relying only on the finishing tone. This matters when wind, conversation, or ferry noise masks audio and you need to know when the footwear pause has ended.

Once the countdown interrupts your preparation, return directly to checking the tread before moving towards the boat or track. If visible soil remains, clean that section again rather than treating the elapsed time as proof that the shoe is ready. Keeping your bag beside you and the next item of footwear within reach makes the transition back to the task clear and unhurried.

Common questions

What can make this short footwear-disinfection interval take longer before a New Zealand island visit?

Deep tread, clinging mud, or seeds trapped around the sole can require another cleaning pass after the timer ends. Wet conditions near the departure point may also leave fresh material on footwear that was already checked.

What should I do if the footwear looks clean before this brief countdown finishes?

Leave the disinfectant in place and wait for the remaining time rather than walking away early. When the countdown ends, inspect the sole once more and return to preparing for the island crossing.
