🧰 Step-by-Step Instructions

Step 1: Clear the Area

Remove everything from under the sink and around the drain. Lay down an old towel or rag to protect the cabinet from water drips or splash.

Step 2: Boiling Water Flush (Easy First Try)

Boil a full kettle or pot of water and slowly pour it down the drain.

✅ Use: For grease-based clogs
⚠️ Don’t try this on porcelain or plastic sinks that can warp.

Step 3: Try the Vinegar + Baking Soda Method

• Pour ½ cup of baking soda into the drain.

• Follow with 1 cup of vinegar.

• Let it fizz for 10–15 minutes.

• Flush with hot water.

🧪 Why it works: The reaction loosens grime and dissolves organic buildup.

Step 4: Use a Sink Plunger

• Fill the sink halfway with warm water.

• Place the plunger directly over the drain.

• Create a seal and plunge firmly for 20–30 seconds.

• Lift quickly — if water drains, you may be done!

💡 Tip: Block the overflow hole (if present) with a wet rag for better suction.

Step 5: Use a Zip-It or Drain Snake Tool

If plunging doesn’t work:

• Insert a plastic Zip-It tool or drain snake into the drain.

• Wiggle and pull upward to remove hair and gunk.

• Repeat as needed.

🧼 Rinse with hot water afterward.

🛒 Tool recommendation:

➡️ Drain Auger / Snake – For tougher clogs

Step 6: Clean the P-Trap (Optional Advanced Step)

If the clog is below the sink:

• Place a bucket under the P-trap (the U-shaped pipe).

• Unscrew slip nuts with your hand or pliers.

• Remove the trap and clean out debris.

• Reattach tightly and test the drain.

⚠️ This step may be messy — gloves and a bucket are essential.

✅ Prevent Future Clogs

• Use a mesh drain strainer

• Avoid dumping grease, coffee grounds, or hair into the sink

• Flush with boiling water every few weeks to break down buildup
