The Plunger Technique
Safety first

- Lay down towels and keep a bucket nearby for messes
- Check for existing leaks under the sink or outside

Simple DIY mixture
What to do:
- Pour baking soda followed by vinegar into the drain.
- Allow the fizzing reaction to work for 15 minutes.
- Rinse with hot water.
Chemical Warning:
Be cautious with store-bought cleaners ALWAYS FOLLOW PRODUCTS INSTRUCTION.
These harsh chemicals are often meant for maintenance, not for clearing total blockages. They can severely corrode your pipes and damage sink surfaces permanently.
If a chemical cleaner fails to clear the clog, the sitting liquid becomes a safety hazard that must be professionally and carefully removed.
Pro Tip:
Never combine different drain products as they can produce lethal gases. Always use gloves, eye protection, and ensure the room is well-ventilated.
