Set the timer to 175 seconds

Online timer for 175 seconds

Start the rinse, leave the wetsuit under fresh running water, and use the next one hundred and seventy-five seconds to put away your towel, board or beach bag. The countdown gives the suit a brief, defined rinse while you handle the sandy gear nearby, rather than standing over it and guessing how long the water has been running.

Keep the countdown page open while you move around, because closing its tab or browser may stop the alert or prevent you from seeing that time has expired. If the phone is likely to be bumped while wet equipment is being sorted, leave it on a dry, stable surface with the screen awake. Returning to the rinse a little early is more useful than assuming a closed page will still signal the finish.

Place the phone close enough to hear over the tap, an outdoor shower, nearby traffic or a windy afternoon at the beach. Raise the alert volume before walking away, but avoid leaving the phone where spray can reach it. When the sound is easy to distinguish from the surrounding noise, the rinse can finish without fresh water running unnoticed while attention is on the rest of the gear.
