German and Brazilian homes use simple ingredients to eliminate fridge and cupboard odors

In Germany, lingering refrigerator smells are often caused by expired food, spills or infrequent cleaning. Recommended steps include unplugging the appliance, discarding spoiled items, washing removable shelves and drawers with warm soapy water, and wiping the interior with a solution of warm water and a tablespoon of baking soda. Door seals should be scrubbed, rinsed and dried before the fridge is re‑stocked.

In Brazil, a low‑cost natural aromatizer for cupboards can be made from dried citrus peels such as orange, lemon or tangerine. The peels are dried thoroughly, placed in breathable sachets or small open containers, optionally mixed with spices, and positioned in drawers or on shelves. The sachets absorb moisture and neutralise odours, providing an eco‑friendly alternative to commercial products.
