Soda crystals are a natural alkali that excels at breaking down organic matter—especially the grease, soap scum, and hair that commonly cause domestic blockages. Why Soda Crystals Work
If soda crystals alone aren't enough, you can add a physical reaction to help dislodge debris:
| | Avoid if | |--------------|---------------| | Greasy kitchen sink blocks | Complete solid blockage (no water movement at all) | | Soap scum & hair buildup | After using chemical drain cleaners (risk of reaction) | | Slow-draining bathroom sinks | Aluminum or galvanized pipes (prolonged use may corrode) |
: Pour crystals down the drain, followed by Citric Acid dissolved in hot water. The resulting fizzing reaction helps shift stubborn grime.
: If the sink is full, remove as much water as possible so the crystals can reach the blockage directly.
Slowly pour 1–2 liters of boiling water directly down the drain. The heat and chemical reaction help break down grease and fat.
Using soda crystals (sodium carbonate) is a highly effective, non-toxic way to dissolve grease, soap scum, and grime in sink drains. Unlike caustic soda, they are gentler on pipes but still powerful enough for most blockages. Step-by-Step Unblocking Guide
Sprinkle about one cup (200–250g) of soda crystals directly into the drain hole. For very slow drains, you can use up to two cups.
Unlike baking soda, which is often used for mild cleaning, soda crystals are more alkaline and powerful. When mixed with hot water, they create a caustic solution that reacts with fatty acids in the grease to "saponify" them, essentially turning the oily gunk in your pipes into water-soluble soap that can be flushed away. Step-by-Step: How to Unblock Your Sink
Leave the mixture to sit for 15–30 minutes (for stubborn blocks, leave overnight). Do not run the tap during this time.
