Can You Flush Kleenex Down the Toilet?
No, don't flush facial tissues like Kleenex. Unlike toilet paper, facial tissues are designed to stay strong when wet—they don't break down quickly in water. This means they can clog pipes, accumulate in sewer systems, and contribute to "fatbergs." Always throw tissues in the trash.
Key Takeaways
- Toilet paper is engineered to disintegrate rapidly when wet.
- "Flushable" wipes are technically flushable—they'll go down—but they don't dissolve properly and cause issues.
- Tissues with lotion, mentholated tissues, and anti-viral tissues are even worse for plumbing.
Explanation
Toilet paper is engineered to disintegrate rapidly when wet. Put toilet paper in water and it falls apart within seconds. Facial tissues are designed for the opposite—to hold together when you blow your nose or wipe tears. This strength makes them problematic for plumbing.
In your home's pipes, tissues can snag on rough spots, existing buildup, or other debris and create clogs over time. Beyond your home, they combine with fats, oils, and other non-flushables in sewer systems to form massive blockages called fatbergs that cost cities millions to remove.
The same applies to paper towels, baby wipes (even "flushable" ones are problematic), cotton balls, and feminine products. If it's not toilet paper or human waste, it belongs in the trash, not the toilet.
You can test this yourself: place a sheet of toilet paper and a facial tissue in separate glasses of water. Stir gently after 30 seconds. The toilet paper will have already broken into pulp, while the tissue remains largely intact even after several minutes. This wet-strength difference exists because tissue manufacturers add a resin called polyamidoamine-epichlorohydrin (PAE) that cross-links cellulose fibers, preventing them from separating in water. Toilet paper deliberately omits this chemical.
The financial risk of flushing tissues adds up. A single plumber visit to clear a household clog runs $150-$350, and if tissues have accumulated deep in your sewer lateral (the pipe connecting your home to the city main), the repair can cost $1,000-$7,000 depending on whether the pipe needs excavation. Renters are not immune either—landlords can charge tenants for plumbing repairs caused by flushing inappropriate items, and the damage is often traceable to specific units in apartment buildings.
Things to Know
- "Flushable" wipes are technically flushable—they'll go down—but they don't dissolve properly and cause issues.
- Tissues with lotion, mentholated tissues, and anti-viral tissues are even worse for plumbing.
- A single tissue occasionally likely won't cause problems, but habits matter.
- Septic systems are even more sensitive to non-degradable items.
- If you have a cold and are going through many tissues per day, keep a small lined wastebasket right next to you instead of making trips to the bathroom—it removes the temptation to flush entirely.
