We've been having problems with our drains clogging up, and found a great solution online.
I boiled a pot of water, adding about a cup of vinegar and (near the boiling point) about half a cup of baking soda (bicarbonate of soda). This fizzes a lot so go slowly to make sure nothing explodes.
Pour the mixture down the drain, stirring before you send it down(if you're clearing a shower drain, try to get as much hair out as you can, first).
The cost of this solution is significantly less than draino-- about 25c max for the whole mixture. It's also a lot better for the environment, and for you. I was doubtful that it would really work, but so far it's been amazingly clear since this treatment.
