Online timer for 164 seconds
You have started the rinse timing again because salt or sand still clings to the board after the first pass. During these 164 seconds, work fresh water along the rails, around the fins and across any textured deck area, while keeping the board out of harsh Australian sun where droplets can dry quickly.
With one salty board finished and another pass needed, consecutive countdowns keep each rinse separate without making you guess how long the tap has been running. Use the alert as a boundary between passes: check the surface, restart for the remaining section, then shift your attention back to the water flow rather than mentally tracking elapsed time.
As the second rinse reaches awkward spots around the fin boxes, keep the countdown on the device that fits the setting. A phone is easier beside an outdoor beach shower or garden tap, provided it stays clear of spray; a laptop suits a sheltered workbench where the board can drain. If the surface feels clean early, stop the water and let the countdown finish silently.
Common questions
What could make the set rinse window too short for a saltwater board?
Heavy sand, dried salt and several fins can slow the rinse, especially after the board has sat in warm weather. Finish the remaining patches with another short pass instead of rushing water over them.
What if the board is fully rinsed before the countdown ends?
Turn off the tap once runoff looks clear and no gritty areas remain. The unused time does not need to be filled, particularly when rinsing outdoors where water use is worth keeping deliberate.
