The answer to 'how to unclog drain cleaning' is to use a plunger, a drain snake, or a baking soda and vinegar solution to clear a clogged drain. Start by removing any debris or hair from the drain opening. Then, use a plunger to create suction and dislodge the clog. If that doesn't work, use a drain snake or auger to reach deeper into the pipe and break up the blockage. For a more natural approach, pour baking soda down the drain followed by vinegar, let it fizz, and then flush with hot water.
Be sure to wear gloves and eye protection when working with drain cleaning tools. Avoid using harsh chemical drain cleaners, as they can damage pipes over time. If the clog persists or you're unable to clear it, it's best to call a professional plumber for assistance.
