Household maintenance tips for refrigerators and water bottles

Various household maintenance tips suggest using common items to address odors and hygiene issues in refrigerators and water bottles.

For refrigerators, placing a bowl of coarse salt inside can help manage odors and moisture. Because salt is hygroscopic, it attracts and retains ambient humidity, which may help reduce localized condensation and delay frost buildup. However, this is not a complete solution; if frost reaches several millimeters in thickness, energy consumption can increase by up to 30%.

Regarding reusable water bottles, persistent odors are often caused by bacteria and residue trapped in the silicone seals and caps rather than the bottle itself. Because silicone is slightly porous and contains micro-folds, it can harbor mold and bacteria if not properly cleaned. Effective cleaning involves using a mixture of hot water, white vinegar, and baking soda to target these specific components.
