The best way to soak the poha is in a sieve. Add the poha to the sieve and hold it under the tap. Rotate the sieve till all the poha is soaked. Set aside to drain.  This takes a maximum of 1 minute which is more than enough to soak it. Let the poha rest while you start tempering the ingredients. But in case you do not have one add the poha to a big bowl and add water for each cup of poha 2-3 bowls swirl around. Drain the water and repeat 2-3 times. The time spent for each rinse is about 30 seconds. The reason for changing the water is to drain out all dirt and impurities.
