Most people don’t realize these 25 things are dangerous to put down the sink

🚫 21. Coconut Oil

Solid at room temperature, it hardens in pipes and causes sneaky clogs.

🚫 22. Nuts and Seeds

Tiny but tough—they don’t break down and can get caught in the drain trap.

🚫 23. Hair

Mostly a bathroom problem, but still relevant: hair binds with soap to form stubborn clogs.

🚫 24. Soap Scum

Not something you “put” down the drain, but frequent use of heavy soaps and shampoos leads to residue that clings to pipes.

🚫 25. Baking Ingredients (e.g., sugar, yeast, baking soda in large amounts)

Excess sugar attracts pests. Yeast can ferment and bubble. Large amounts of baking soda can harden and contribute to blockages.

🛠️ What to Do Instead

• Use a drain screen to catch solids and food particles.
• Compost when possible—coffee grounds, eggshells, and veggie scraps are compost gold.
• Pour leftover grease into a jar, let it solidify, and throw it away.
• Dispose of chemicals and medications at proper hazardous waste facilities or pharmacy take-back programs.

🌍 Protect Your Pipes, Wallet, and the Planet

Your sink isn’t a catch-all disposal system. Being mindful of what goes down the drain saves you from expensive plumbing problems—and helps protect local water systems and wildlife.

So next time you’re tempted to rinse something questionable down the sink, pause and remember: just because it disappears from sight doesn’t mean it’s gone.
