Here is the deep dive on how to use these two minerals to keep your pipes flowing, why they work, and the one place you should never use them. To fix a drain, you have to understand what is clogging it. In kitchens, it’s grease, oils, and emulsified food sludge. In bathrooms, it’s soap scum, hair, and mineral deposits.

Give your drains a dry salt scrub tonight. Your future self, standing in a dry shower with no standing water, will thank you. Have you tried the salt-and-baking-soda method? Or are you still loyal to the vinegar volcano? Let me know in the comments below.

If you’ve heard the internet hack of pouring baking soda and vinegar down the drain, you’ve only heard half the story. In fact, that fizzing reaction neutralizes both ingredients, rendering them mostly useless for cleaning.

While those bubbles might knock a loose piece of debris loose, they are too soft to scour pipe walls. You are essentially pouring expensive, flavored water down your drain.

Salt accelerates rust. If your cast iron pipe has a tiny pinhole leak, the salt will find it and widen it. For old, corroded metal, stick to boiling water only, or call a professional. Baking soda and salt are for maintenance and minor organic clogs (grease, soap scum, toothpaste, food residue).
