Soda Crystals Unblock Drain -

: Never mix soda crystals with acidic cleaners (like vinegar) in a closed pipe, as the reaction can cause pressure buildup.

: Pour a full kettle of boiling water down the drain to soften any hardened grease and debris.

For stubborn blockages, repeat the process 2–3 times before calling a plumber.

The mixture will fizz and bubble. Cover the drain with a plug to force the pressure downward toward the blockage.
