10 Surprising Items You Must Never Pour Down the Drain

Strands of hair behave like microscopic fishing nets. They drift down the drain, snag on rough pipe edges, and weave into thick ropes that catch soap scum, conditioner residue, and lint.
A single shower can send hundreds of hairs swirling into the trap. Install a simple mesh screen over the drain and empty it after each use. When brushing, knock loose hairs straight into a bin. Doing so prevents the slow, silent buildup that eventually forces you to pour harsh chemicals—or your savings—into a clogged drain.
