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.
Step 2 – Let it set
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.
