Blocked sinks typically have unpleasant odours or slow-draining water, which usually indicate a clogged drain. Thankfully, a simple natural remedy can solve this problem. Drains are inevitable to get clogged due to daily scraps of food, soap, and greasy residues, eventually resulting in a blockage.

Ollie, an interior expert at Bathroom Takeaway, suggests opting for a non-chemical cleaning solution by recommending soda crystals and hot water as one of the most effective ways to tackle a blocked drain. He said: “Try using soda crystals, also known as washing soda. It’s a simple and inexpensive solution that can effectively clear even the toughest sink blockages.” Soda crystals are highly alkaline, and they excel at dissolving acidic grease and fat blockages, making it easier to flush away the build-up and clear the blockage.

Considering alternative cleaning solutions, while vinegar and baking soda are commonly suggested for various household cleaning roles, they’re not recommended for unblocking drains.

Vinegar, being acidic, and baking soda, mildly alkaline, cancel each other out upon mixing, creating a fizz that lacks the potency to cut through grease.

Moreover, although vinegar is mild, its acidity could damage pipe materials over time, whereas soda crystals pose a much gentler risk to plumbing.

Soda crystals are engineered to be a potent degreaser that can dissolve blockages, all while being eco-friendly and devoid of harsh chemicals.

Start by boiling a full kettle and gradually pour the hot water into the sink.

Wait for a few minutes to allow the water to drain. Once the water has drained away, pour a generous cup of soda crystals down the drain.

Let the soda crystals sit for about five minutes to work their magic on the grease buildup. 

Refill the kettle and bring it to a boil, then cautiously pour the boiling water down the plug once more.

Continue repeating these steps until the drain is fully unblocked, and you should notice improvements each time you do this.
