Need to unclog a drain? This method is the simplest and most cost-effective!

II. Complete Step-by-Step Instructions: Follow along, and you're done in 10 minutes!
Step 1: Preparation
Tools List:
50g baking soda (about 4 tablespoons)
100ml distilled white vinegar (or regular vinegar if unavailable)
1 kettle of boiling water (about 500ml)
Measuring cup, container, rubber gloves (optional)
Note: If the drain is completely still, you may need to gently press down with a rubber plunger to partially unclog it.
Step 2: Initial Rinse
Slowly pour a small amount of hot water (do not boil) down the drain to soften any remaining grease in the pipes.
Key Tip: The hot water temperature should not be too high to avoid deforming the PVC pipes.
Step 3: Add Baking Soda
Pour 50g of baking soda directly into the drain hole and let it sit for 5 minutes to allow the powder to absorb the grease.
Step 4: Add Vinegar, Start the Reaction
Slowly pour the vinegar down the drain. Foaming and a hissing sound will immediately appear (this is a normal reaction).
Tip: You can temporarily cover the drain hole with a damp cloth to allow the air bubbles to work effectively in the pipes, enhancing cleaning power.
Step 5: Let it sit and rinse
Wait 1-2 hours to allow the acid-base reaction to completely break down the dirt.
Flush the pipes with plenty of hot water to remove any residue. If the water flow rate increases significantly, the cleaning was successful!
