Rinse the rice in large bowl of water, and pick out anything that shouldn't be in there.
Strain the rice.
Put the water, rice, and salt in a pot.
Turn the heat to high, and bring to a boil.
Cover, lower the heat, and simmer 18-20 minutes. Add 3-5 minutes for brown rice. Try to not lift the lid, instead give the pot a shake to feel if the contents are sliding around - that means there's still liquid in there and it's not sticking/burning.
Remove from heat, and let rest for 10 minutes.
Fluff with a fork, then serve.
