Overview
- Chip.de reports that some plumbers commonly clear sinks by pouring roughly half a bottle of dishwashing liquid into the drain, filling the basin with hot water, then releasing it to push the clog through.
- The approach uses surfactants and heat to loosen grease and food residues, with results sometimes taking a few minutes to become visible.
- Additional tips include adding a handful of salt and waiting about 30 minutes before rinsing with boiling water, or using a dishwasher tab dissolved in hot water followed by a thorough hot flush.
- These remedies target light buildups and usually do not resolve hair clogs, heavy limescale or deep blockages, which may require a plunger, a drain snake, siphon cleaning or professional help.
- Advisers warn that many chemical drain cleaners are aggressive and can harm seals, pipes, health and the environment, recommending strainers and periodic hot‑water maintenance to prevent new deposits.
