Here's the whole handout -- I refer to this so often I might as well just type it and then link to this post...!

Saltwater washes (nasal saline lavage or irrigation) for nose and sinuses
Saltwater washes (saline lavage or irrigation) help keep the nasal passages open by washing out thick or dried mucus; they can also help improve the function of cilia that help clear the sinuses. This can help prevent the spread of infection to the other sinuses and reduce postnasal drip. It also can make the nose feel more comfortable by keeping the mucous membranes moist.
Nasal irrigation can be done several times per day, and is frequently performed with a syringe or a Water Pik device (the attachment is purchased separately). You can buy saline nose drops (such as Ocean or Salinex) at a pharmacy, or you can make your own saline solution by mixing 1 tsp (5 g) of salt in 1 pint (473.5 ml) of water and adding a pinch of baking soda. It is best to use Morton Coarse Kosher Salt or Springfield plain salt because table salt may have unwanted additives. Use the saline solution at body temperature. To apply homemade saline solution:
- Fill a bulb syringe with saline solution, insert the tip into your nostril, and squeeze gently.
[list]For young children, use small commercial spray bottle, such as the one from Ocean Spray or nasal steroid spray and squirt it as many times as the child will tolerate. Do not force the child to lie down, have the child sit or stand.
- The saline wash should go through the nose and out the mouth [transcriber note -- this rarely happens in my experience. more often through one nostril or out the other, or in and out of one nostril].
- While irrigating the nose, it is best to stand over the sink and irrigate each side of your nose. Aim the stream toward the back of your head, not at the top of your head.
- Blow your nose gently after the saline wash.
- Repeat several times every day. Consider using this before you try other nasal medications.[/list]
If the solution stings, use less salt. In the beginning, or for children, it is best to start with a weaker salt mixture. It is not unusual to initially have a mild burning sensation the first few times you irrigate. If you are using a nasal steroid spray, you should use it after the salt water wash.
