Step 1 – Enter the vinegar and baking soda
Pour vinegar down the drain. I follow that up with a bit of baking soda down the same drain, then quickly close it up with the sink stopper. Keep the cap in place until the bubbling reaction subsides.
After boiling is complete, leave the tub for 30 minutes.
Step 3 – Rinse with warm water
After half an hour, bring a kettle or pot of water to a boil. Remove the sink stopper and carefully pour boiling water down the drain. Hot water will help remove remaining blockages, as will baking soda and vinegar residue.
