How to fix a clogged laundry sink drain caused by detergent buildup?

 

Many homeowners have found that following these steps leads to effective drain maintenance—whether you’re in St. Louis or Nashville, a practical tip that has worked in various settings.

  STEP 1: PREPARATION  

• Gather supplies such as baking soda, white vinegar, a kettle or pot to boil water, a plunger or drain snake, rubber gloves, and a cloth or paper towels.
• Ensure the area around the sink is dry and clear of clutter. Turn off any nearby water sources if necessary to prevent additional water from interfering with the cleaning process.

 
STEP 2: CLEAR THE DRAIN ACCESS
 

• If your laundry sink has a removable drain stopper or filter, take it out for easier access.
• Inspect the drain opening for visible detergent residue or debris, and remove any clogs you can reach by hand or with a cloth.

 
STEP 3: APPLY NATURAL CLEANING SOLUTION
 

• Pour about ½ cup of baking soda directly into the drain. The baking soda will help break down the detergent buildup and neutralize any odors.
• Slowly add 1 cup of white vinegar. You should notice a fizzing reaction as the vinegar and baking soda work together to dissolve the buildup.
• Allow the mixture to sit in the drain for 15-20 minutes so it can penetrate and loosen the detergent residue.

 
STEP 4: FLUSH WITH HOT WATER
 

• Boil a kettle or pot of water. Once the cleaning solution has had time to work, carefully pour the boiling water slowly down the drain.
• The hot water helps to flush out the loosened detergent mixture and any remaining buildup in the pipes.

 
STEP 5: USE A PLUNGER OR DRAIN SNAKE IF NEEDED
 

• If the drain is still not flowing freely, use a plunger to create suction and dislodge any stubborn clogs. Make sure there is enough water in the sink to cover the plunger’s cup for effective plunging.
• If plunging does not clear the clog, try using a drain snake. Insert the snake into the drain and twist it gently while pushing forward, then pull it out to remove the detergent buildup and other debris.

 
STEP 6: MAINTENANCE AND PREVENTION
 

• After the drain is clear, periodically flush it with hot water to prevent future detergent buildup.
• Consider using less detergent per load or ensuring the detergent is well-dissolved in water before adding it to the washer to minimize residue in the sink.
• Install a drain strainer or cover to catch particles and prevent clogs from recurring.
