Unclog a Drain with Vinegar: Fake News? 

Yes.  The vinegar isn’t really unclogging your drain at all.  It’s the boiling water.  Boiling water dissolves the gunk and grease that is holding the clog together.  The clog slides down the drain once the boiling hot water dissolves the gunk.   

Don’t waste your vinegar.  Instead, install a debris catcher in the sink drain to capture any chunks before they go down the drain and dispose of all greasy items in the trash. 


You can unclog a drain with vinegar, but really, it’s the boiling hot water that is doing all the work.  Save your vinegar and just pour boiling water down your drains to clear out clogs fast.
