## Most People Don’t Realize These 25 Things Are Dangerous to Put Down the Sink

Our kitchen sink is a hardworking hub where we wash dishes, prep food, and clean up after meals. But did you know that many common items we casually rinse down the drain can cause serious problems? From clogged pipes to environmental hazards, putting the wrong things down your sink can cost you time, money, and even harm the planet.

Here are 25 surprising items you should **never** put down your sink—and why avoiding them can save you from headaches and costly repairs.

### 1. Grease, Fat, and Cooking Oils

These might seem harmless when warm, but they solidify in pipes, causing blockages. Instead, collect and dispose of grease in the trash.

### 2. Coffee Grounds

Though they’re biodegradable, coffee grounds clump together and can clog pipes over time. Compost them instead.

### 3. Eggshells

Shells don’t dissolve and can accumulate in traps, leading to clogs. Add them to your compost bin.

### 4. Pasta and Rice

These foods expand in water and can create blockages as they swell inside pipes.

### 5. Potato Peels

Starchy peels can stick to pipes and cause buildup. Best to compost or dispose of them with regular trash.

### 6. Flour and Baking Ingredients

Flour forms a paste when wet, sticking to pipes and causing clogs.

### 7. Candy and Gum

Sticky sweets can cause immediate clogs by catching debris and buildup.

### 8. Paint and Solvents

Toxic and harmful to the environment, these chemicals should never be poured down the sink.

### 9. Household Cleaners in Excess

Some cleaners can damage plumbing and septic systems if poured in large quantities. Use sparingly and follow instructions.
