The most effective DIY drain cleaning method is baking soda and vinegar: pour 1/2 cup baking soda, followed by 1/2 cup white vinegar, wait 30 minutes, then flush with boiling water. For stubborn clogs, use a drain snake. Call a professional if multiple drains are slow or DIY methods fail after 2-3 attempts.

Clogged and slow drains are among the most common plumbing issues Toronto homeowners face. From hair-filled bathroom drains in Yorkville condos to grease-clogged kitchen sinks in Leslieville townhouses, drain problems don't discriminate by neighbourhood or housing type.
The good news? Most minor drain clogs can be cleared with simple DIY methods—no expensive plumber visit required. After 25 years of drain cleaning across the GTA, I've seen which home remedies actually work and which are internet myths that waste your time (or damage your pipes).
This guide covers 7 proven drain cleaning methods, organized from simplest to most advanced. I'll also explain when DIY isn't enough and you need professional help—saving you time, money, and potential water damage.
7 DIY Drain Cleaning Methods That Work
Boiling Water Flush
You'll Need:
- Kettle or pot
- 2-3 litres of water
- Boil 2-3 litres of water in a kettle or large pot
- Remove any visible debris from the drain opening
- Pour boiling water directly down the drain in 2-3 stages
- Wait 5 seconds between each pour to let water work
- Repeat 2-3 times if drain is still slow
Do NOT use boiling water on PVC pipes (common in newer Toronto construction) or if you have a porcelain sink. Hot—not boiling—water is safer for these materials.
Baking Soda & Vinegar
You'll Need:
- 1/2 cup baking soda
- 1/2 cup white vinegar
- Boiling water
- Drain stopper or rag
- Remove the drain stopper and clear any visible debris
- Pour 1/2 cup baking soda directly into the drain
- Follow immediately with 1/2 cup white vinegar
- Cover the drain with a stopper or wet rag to contain the fizzing
- Wait 30 minutes (or overnight for stubborn clogs)
- Flush with boiling water for 2-3 minutes
For extra cleaning power, add 1/2 cup salt with the baking soda. The abrasive salt helps scrub pipe walls while the chemical reaction breaks down buildup. This is especially effective for Toronto's hard water mineral deposits.
Drain Snake (Plumber's Auger)
You'll Need:
- Hand-crank drain snake (12-25 feet)
- Rubber gloves
- Bucket
- Old towels
- Remove the drain stopper and P-trap if accessible
- Insert the snake slowly into the drain opening
- When you feel resistance, rotate the handle clockwise
- Push through the clog while continuing to rotate
- Pull the snake out slowly, cleaning debris as you go
- Run hot water for 5 minutes to flush remaining material
Where to buy: Canadian Tire, Home Depot, and most Toronto hardware stores carry drain snakes for $15-40. The Zip-It drain cleaning tool ($5-8) works well for bathroom sink and tub drains.
Wet/Dry Vacuum Method
You'll Need:
- Wet/dry shop vacuum
- Tight seal over drain
- Set your shop vac to liquids mode
- Create a tight seal over the drain opening
- Turn on the vacuum at highest suction setting
- The powerful suction can pull out stubborn clogs
- Check the vacuum canister for retrieved debris
This method works great for retrieving dropped items like jewelry, earring backs, or small toys that fell down the drain. Much better than taking apart the P-trap!
Dish Soap & Hot Water
You'll Need:
- 1/4 cup dish soap (Dawn works best)
- Large pot of hot water
- Squirt 1/4 cup dish soap directly into the drain
- Boil a large pot of water (2-3 litres)
- Slowly pour the hot water down the drain
- Wait 15 minutes
- Run hot tap water for 5 minutes to flush
This is my go-to recommendation for Toronto kitchen drains. The dish soap emulsifies grease while hot water melts and flushes it away. Use this weekly as a preventive measure.
Wire Hanger Technique
You'll Need:
- Wire coat hanger
- Pliers
- Rubber gloves
- Straighten a wire coat hanger
- Create a small hook at one end using pliers
- Carefully insert the hook end into the drain
- Fish around to catch hair and debris
- Pull out the gunk slowly (it will be gross)
- Flush with hot water when done
Go gently to avoid scratching porcelain or pushing debris deeper. This works best for clogs within the first 6-12 inches of the drain.
Enzyme Drain Cleaners
Recommended Products:
- Bio-Clean (available at plumbing supply stores)
- Green Gobbler Enzyme
- Earthworm Drain Cleaner
- Pour enzyme cleaner according to package directions
- Let sit overnight (bacteria need time to work)
- Run hot water in the morning
- Repeat monthly for maintenance
Unlike chemical cleaners, enzyme-based products use natural bacteria to digest organic matter. They're safe for all pipe types and septic systems—ideal for Toronto homes with older plumbing in The Beaches, Riverdale, and Roncesvalles.
Cleaning Tips by Drain Type
Different drains face different challenges. Here's how to tackle each type:
🍳 Kitchen Sink
Common culprits: Grease, food particles, soap scum
- Never pour grease down drain
- Use strainer to catch food
- Run hot water after every use
- Weekly: Dish soap + hot water flush
🚿 Bathroom Sink
Common culprits: Hair, toothpaste, soap residue
- Remove pop-up stopper monthly
- Clean hair from stopper weekly
- Monthly: Baking soda treatment
- Use mesh drain cover
🛁 Bathtub/Shower
Common culprits: Hair, soap scum, product buildup
- Install hair catcher ($5-10)
- Remove and clean drain cover weekly
- Enzyme cleaner monthly
- Snake every 6 months if needed
🏠 Floor Drains
Common culprits: Dust, debris, dried P-trap
- Pour water weekly to keep P-trap wet
- Remove grate and clean quarterly
- Check for root intrusion annually
- Install backwater valve for protection
DIY vs Professional Drain Cleaning
When should you tackle a clog yourself, and when is it time to call in the pros?
| Situation | DIY Solution | Professional Needed |
|---|---|---|
| Single slow drain | ✓ Try methods 1-7 | After 2-3 failed attempts |
| Hair clog near surface | ✓ Snake or hanger | If snake doesn't reach |
| Kitchen grease buildup | ✓ Hot water + soap | If completely blocked |
| Multiple slow drains | ✗ | ✓ Main line issue |
| Sewage backup | ✗ | ✓ Emergency service |
| Gurgling sounds | ✗ | ✓ Venting issue |
| Tree root intrusion | ✗ | ✓ Hydro jetting/camera |
When to Call a Professional Plumber
Some drain issues require professional equipment and expertise. Call a licensed plumber if you experience:
- Multiple slow drains – Indicates a main sewer line problem
- Water backing up in other fixtures when using drains
- Sewage odours that persist after cleaning
- Recurring clogs in the same drain (may indicate pipe damage)
- Gurgling sounds from drains or toilets
- Slow drains throughout the house
- Tree roots suspected (common in older Toronto neighbourhoods like High Park, Rosedale, Forest Hill)
Many homes in The Annex, Cabbagetown, and Parkdale have original clay or cast iron pipes from the early 1900s. These require gentler cleaning methods—avoid chemical cleaners that can accelerate deterioration. Annual professional camera inspections are recommended for homes over 50 years old.
Why We Don't Recommend Chemical Drain Cleaners
Products like Drano and Liquid-Plumr might seem like easy solutions, but professional plumbers universally advise against them:
- Pipe damage: Caustic chemicals generate heat that can warp PVC or deteriorate old metal pipes
- Incomplete clearing: Often only opens a small channel, leaving buildup on pipe walls
- Safety hazard: Dangerous if you later call a plumber who has to work with chemical residue
- Environmental harm: Contaminates wastewater treatment systems
- Septic system damage: Kills beneficial bacteria in septic tanks
For Toronto homes—especially those with older plumbing in established neighbourhoods—natural methods and mechanical cleaning are always safer and more effective long-term solutions.
