Want a fresher toilet without harsh chemicals? Try salt. It’s cheap, eco-friendly, and surprisingly effective for simple upkeep.
Salt’s coarse crystals act like a gentle scrub. They help loosen grime, encourage toilet paper to break down, and naturally absorb odors. While it’s not a cure for clogs, it can prevent small issues from building up.

To use, pour about one cup of coarse salt—rock, kosher, or sea—into the toilet bowl. Let it sit. Overnight is best, since the crystals need time to work.
In the morning, scrub with a toilet brush and flush. Done. Repeat every few weeks for easy maintenance.

Why does it work? Salt’s mild abrasiveness helps lift mineral stains and buildup. Its natural deodorizing qualities reduce lingering smells. And by softening paper over time, it encourages smoother flushing.

Keep it simple: only use salt in the bowl. Avoid putting it in the tank, where it can damage metal parts. For extra cleaning power, mix in half a cup of baking soda before the overnight soak.
