• Plumber-endorsed method: pour about half a bottle of dishwashing liquid into the drain, plug the basin, fill with hot water, then release the stopper carefully so the hot surge can dissolve buildup, allowing a few minutes for flow to improve.
• For a targeted reaction, add roughly 3–4 tablespoons of baking soda to the drain, pour in about 100 ml of vinegar, wait around 15 minutes as it foams, then flush thoroughly with boiling water.
• A hand‑sized dose of table salt left to sit for about 30 minutes and followed by boiling water can ease light grease and soap deposits and serves as an easy maintenance rinse in kitchen sinks.
• As another light‑clog option, dissolve a dishwasher tab in a cup of boiling water, pour the solution in stages, let it work for about an hour, then rinse hot, which is most effective on food and fat residues.
• Guides stress limits: home remedies work best on organic build-up, while hair, plastics or deep blockages often require a plunger, a drain snake or a professional; a simple drain strainer helps prevent recurring clogs.
