Let the reaction sit for 15 to 30 minutes. If the clog is severe, leave it for an hour or even overnight.

This is the secret step most people miss. Immediately cover the drain opening with a stopper or a damp rag. You want to trap the fizzing reaction inside the pipe so the pressure forces the clog to break up.

You already have the best drain cleaner in your pantry:

Boil a full kettle of water. Remove the stopper and slowly pour the boiling water down the drain. This washes away the dissolved gunk and the vinegar residue. Does it actually work for tough clogs? Yes , for organic clogs like grease, soap scum, and food residue. No , for solid objects (a child’s toy) or massive hair plugs.

Scoop 1 cup of baking soda directly into the drain. Try to get it past the strainer and down the pipe.

So next time your sink gurgles at you, skip the hardware store. Go bake a cake first—then use the baking soda to fix your pipes. Have you tried this natural method? Let me know in the comments if the fizzing volcano saved your sink!

Before you reach for the harsh chemical cleaners (you know, the ones that burn your nostrils and warn you not to touch the bottle), step away from the cupboard.
