A homeowner has tested whether salt or baking soda is more effective at removing window condensation, with a clear winner emerging. The experiment, conducted over two nights, used 125g of each substance placed on the same windowsill.
The salt, costing just 12p for the amount used, hardened overnight, indicating it absorbed moisture. However, the windows remained as foggy as usual, requiring the usual morning wipe-down with a squeegee.
In contrast, the baking soda, costing 30p, proved far more effective. The next morning, there was no condensation on the window, and the powder had only slightly hardened, suggesting it can be reused several times.
The homeowner noted that both substances act as natural dehumidifiers, but only baking soda delivered noticeable results. The test was conducted under identical temperature conditions to ensure fairness.
This simple, low-cost hack could help households reduce energy use by relying less on dehumidifiers during colder months.
