This straightforward technique is astonishingly effective. Grab a wire coat hanger and straighten it out. Bend either end of the straightened hanger to create a hook. Push the hanger hook-first past the drain cover and try to fish for all the stuff that’s clogging the drain. You might see a ton of nasty gunk when you pull the hook out.
But be careful – you don’t want to push all the junk further; you want to pull it out. When you feel you’ve reasonably cleaned the drain, run some hot water and you have yourself a clean drain.
Mix 1/3rd cup of baking soda and vinegar each in a measuring cup. You’ll see it fizz almost instantly – but don’t hold up, quickly pour it down your clogged drain. The fizzing action is helpful in removing hair, gunk, and grime that’s been clogging your drain. Let it sit for at least an hour, or even through the night if possible. Flush the drain with some hot water and that should clear things up. You could also try to first put baking soda down your drain, and then chase it with some vinegar.
Most people think of plunging as a toilet-only solution, but it works just as effectively for clogged drains as well. The age-old simple technique is the easiest way to unclog any household drain. Once you’re done unclogging, be sure to run about 2-3 liters of hot water just to ensure all the debris gets washed away.
Before using caustic soda, grab a pair of rubber gloves and some protection for your eyes. Caustic soda (Sodium Hydroxide) can cause severe chemical burns. It’s easily available at all hardware stores, but practice caution while handling it. Fill a mop bucket with ¾ gallon of cold water, and pour in about 3 cups of caustic soda. Stir the mixture well with a wooden spoon until it begins to fizz and heat up. Empty it into your clogged drain and let it sit for about half an hour, and then run some hot water into the drain. If required, repeat the process.
