Is there any home-made recipe for relieving a congested nose?

Table salt: Boil some water, take 7 ounces of that water and add 1/4 teaspoon of table salt and let it cool off. There is your home made remedy. The only thing is , you have to make fresh ones every 2-3 days. You have to account for cost of water, gas or electric bill. Is it worth it? I would recommend buying saline solutions otc which is cheaper, more practical and you can keep till its expiration date!
