Web timer for 23 seconds
After a swim off a Philippine beach, you can leave your fins under fresh running water for 23 seconds and simply wait for the signal. Let the stream reach the foot pockets while you stand still, rather than watching the changing numbers. This brief pause gives the fresh water time to carry loose salt and sand away.
With both fins needing a rinse, separate countdowns keep each turn consistent. Rest one fin beneath the tap or outdoor shower, wait for the alert, then switch and begin again. Repeating the same interval also helps when sand is trapped around both straps, without making you estimate a different pause for every fin.
While the water runs, look away from the screen and notice one fixed detail nearby, such as a tile line or the shadow beside your feet. Count three slow breaths if you need something to occupy the pause, but leave the fin still until the sound. The alert can mark each changeover without requiring you to follow every number.
Frequently asked questions
Should the rinse run longer when sea salt has dried on the fins in Philippine heat?
Yes, dried salt or sand caught near a buckle may need another full interval. A fin rinsed soon after leaving the sea may be clear when the first alert sounds.
What if the fin looks clean before the countdown ends?
You can let the remaining fresh water pass over the foot pocket and strap. If gritty water is still draining at the alert, repeat the same interval instead of guessing a shorter extension.
