Rinsing rice is important, but it’s something people tend to pass over. It removes some of the starch, and makes rice fluffier. The Japanese have special rice-rinsing bowls for this:

I’ve been rinsing rice for over 30 years now. Especially brown rice which is really quite dirty. I use a deeper pot swirl the rice around with my hand. Change the water a few times at least. Your brown rice will have never tasted so good or been more fluffy.
