A home maintenance journalist has tested two kitchen staples to combat window condensation, finding baking soda more effective than salt. The experiment, conducted on consecutive nights with identical conditions, aimed to reduce moisture buildup without relying on energy-intensive dehumidifiers.
Using 125g of salt (costing 12p) placed near a window, the writer observed that while the salt hardened—indicating moisture absorption—the windows remained as foggy as usual. The salt hack, despite its low cost, failed to make a noticeable difference.
In contrast, 125g of baking soda (costing 30p) placed in the same spot overnight resulted in no condensation on the window the next morning. The powder only slightly hardened, suggesting it can be reused several times before replacement.
The writer noted that both products act as natural dehumidifiers, but baking soda proved superior in this test. The findings offer a low-cost alternative for managing condensation, particularly in older properties prone to dampness.
