I have tried metal hanger wire but nothing comes out and I have tried drano.
There's a liquid unclogger sold in supermarkets. In the Philippines, we call it liquid sosa. It's very effective. Before you put the chemical make sure that your sink has been drained thoroughly. Put around 250ml of the chemical and wait for 15 minutes. It usually dissolves hair, grime and grease.
While looking under the sink you will see a U shaped piece of pipe, this is call the trap. Remove it and remove the offending matter that may have gathered there. If there are no debris then you need to remove the sink stopper and remove the accumulated junk from it. You should be good to go after that.
my drain at uni has clogged up really badly a few times before! i don't know what country you live in so you might not be able to get it, but in the uk there is something called buster bathroom drain clear. but most kind of drain-clear products should work fine if you give them long enough! if it says on the bottle pour down the drain and leave for 15 minutes or an hour or so, i'd leave it for a good few hours, and use a really good amount, overnight is what i tend to do. overnight it goes from being almost completely blocked to working just fine in the morning! hope this helps!!
Plugged drains are most likely to occur in three specific places: curved sections of pipes called “traps” that exist underneath sinks, tubs and showers; the internal passages within a toilet; or somewhere inside the main drainpipe leading away from your home. Before you spend a lot of time trying to unplug a sink or toilet, and regardless of where the blockage seems to be located, start with a simple check: Run some water down the other drains in your house. Do the others flow freely? If not, your trouble probably involves more than meets the eye and could actually be part of a systemic problem. Before you try to clear what looks like a small, localized blockage, take a quick look at the big picture. You’ll either know you’re on the right track or save yourself from wasting time trying to solve the wrong problem. Sink, Tub or Shower Drains The most likely spot for a sink drain to clog is about 6 inches below the drain opening in a section of curved pipe called the trap. It’s an essential feature of every drain, but potentially troublesome, too. Traps keep nasty (and lethal) sewer gases from wafting up into your home by retaining small amounts of water in the U-shaped bottom section. This water seals the pipe opening so gases can’t sneak past. Curves of any sort in a drainpipe, especially as tight as those in a trap, encourage blockages. This is where the vast majority of sink, tub and shower blockages occur.
I have to do this every 6 months thanks to my wife's long hair falling in. There are probably two ways. First see if you stopper simply pulls or twists up and out. Next look under the sink and see if there is a metal rod that connects to the straight pipe coming down from your drain. If so, disconnect this rod from the pipe to allow the stopper to come out. Then pull the stopper up and out of the drain. Most of the clogged mess should come with the stopper. Clean it off in your bathtub (your sink will leak if you use it before reconnecting the stopper rod). Then reassemble and test it out. If it's still clogged you'll have to go onto the next section. If the first part doesn't work or your stopper doesn't come out, look under your sink and see if there is a seperate section of curved pipe (probably plastic) connecting to the straight pipe that goes up into the sink and to the pipe that leads out behind the sink. That section of pipe shold have joints on either end (round or hexagonal) that you can loosen (with your hand or a wrench) and take out that curved pipe. But first, put a bucket underneath so you don't make a mess. Now you can take it out and clean it out in your bathtub. There might be stuff stuck in the straight pipe coming down from your sink and you can use your hanger here to pull stuff out.
