It could be ordinary bathroom use, residue under the rim, buildup in difficult-to-clean areas, a dirty toilet brush, poor ventilation, or even a plumbing problem.
A small amount of salt isn’t going to solve a sewer-gas issue or a damaged plumbing seal.
However, using salt as part of a broader cleaning routine may help remove some residue that contributes to unpleasant smells.
The important distinction is this:
Salt may contribute to cleaning, but it isn’t an odor diagnosis or a plumbing repair.
Why Do Mineral Deposits Appear in Toilets?
Another reason people experiment with household cleaning methods is mineral buildup.
If your home’s water contains significant amounts of minerals, you may eventually notice discoloration or crusty deposits around the waterline or other areas.
Hard-water deposits can be stubborn.
Calcium and other minerals may accumulate over time, creating white, gray, yellowish, or brownish marks.
Salt alone isn’t the most effective solution for serious mineral scale.
