Toilet odors usually come from bacteria, hidden residue under the rim, or mineral buildup in the waterline. Even if the bowl looks clean, germs thrive where a brush can’t reach. Each flush can release those odors and sometimes even spread bacteria into the air. The real danger is that ignoring the smell means ignoring bacteria, and over time that leads to stains, buildup, and extra scrubbing later.

Air fresheners and tablets may seem like a quick solution, but they only mask the problem. It’s like spraying perfume on a dirty shirt — nicer for a moment, but the dirt is still there.
