Plumbing experts have identified a simple, natural method to clear blocked drains in just 10 minutes using soda crystals, a common household product that outperforms popular vinegar and bicarbonate of soda hacks.
Why Soda Crystals Work Better Than Vinegar and Bicarb
According to AC Plumbing, soda crystals contain sodium carbonate, an alkaline compound that dissolves grease and fatty residues when activated with hot water. Unlike acidic drain cleaners or the vinegar-and-bicarb mixture, soda crystals break down grease bonds through an alkaline reaction without producing corrosive fumes.
Most household drain blockages consist of grease from food residue or soap, which solidifies into an oily clog. Many homeowners mistakenly rely on white vinegar and bicarbonate of soda, a popular social media cleaning hack. However, combining these two produces only a weak fizzy reaction that generates salt. While the fizzing can dislodge bits of food, it lacks the strength to break down grease effectively.
How to Unblock a Drain with Soda Crystals
If the sink is severely blocked, remove as much standing water as possible so the soda crystals can reach the pipes. For a relatively clear drain, simply add two to four tablespoons of soda crystals directly into the plughole.
Next, fill a kettle to capacity, bring it to the boil, and pour the boiling water down the plughole. This activates the soda crystals and helps loosen the grease within the drain.
Leave the sink undisturbed for at least 10 minutes to allow the crystals sufficient time to break down the grease. After the time has elapsed, refill the kettle and pour the boiling water down the plug to flush the blockage away.
For particularly stubborn blockages, you may need to repeat this process once or twice more to fully eliminate the clog.
Benefits of Using Soda Crystals
Soda crystals offer a natural solution to clearing blocked drains, as their alkaline properties rapidly break down fat molecules found in grease, allowing any blockage to be effortlessly flushed away. This method is swift, efficient, and avoids harsh chemicals. Additionally, soda crystals are widely available in supermarkets and cost approximately £2.
As drains frequently become blocked during summer due to melted ice cream, salad scraps, and grease from burgers, addressing the issue promptly is vital to prevent odours that attract flies. Soda crystals provide a reliable, natural alternative to expensive chemical cleaners or ineffective social media hacks.
