For a long time considered merely waste after brewing a cup, coffee grounds have found a new use around the house. Among the increasingly circulated household tips, the mix with baking soda is attracting particular attention. This combination, easy to prepare and inexpensive, fits a broader aim of favoring simpler solutions for daily upkeep. Without the need to purchase a specific product, it can notably clean certain surfaces and limit unpleasant odors that tend to accumulate in the most-used rooms, such as the kitchen.
A cleaning tip that relies on the properties of coffee and baking soda
The value of this pairing rests primarily on the complementarity of the two ingredients. Baking soda is known for its cleaning and degreasing properties, while the coffee grounds provide a mechanical action thanks to their slightly grainy texture. Together, they form a paste capable of helping to eliminate certain residues on surfaces that are not overly delicate, such as pots, pans, or cutting boards marked by grease traces. The coffee also plays a role in fighting persistent odors, particularly those that can linger in a refrigerator, a trash can, or on hands after handling garlic, fish, or onions, reports the site Okdiario.
This home hack also appeals because it rests on a principle different from traditional air fresheners. Baking soda does not merely aim to mask a bad odor with a stronger scent: it acts by neutralizing certain compounds responsible for unpleasant fumes. The coffee grounds themselves possess a porous structure that allows them to retain part of the odor molecules. Thanks to these two distinct mechanisms, the mixture can be used as an auxiliary solution to maintain certain spaces in the home while giving a second life to an ingredient often discarded after use.
This cleaning method makes it easy to clean and deodorize the home
To prepare this household recipe, nothing could be simpler: mix about two tablespoons of coffee grounds (preferably lightly dried) with one tablespoon of baking soda. A little water can then be added to obtain an easy-to-apply paste. This preparation can be used to gently scrub surfaces covered in dirt or grease before a thorough rinse. The mixture can also be used in dry form, placed in a small open container in the refrigerator or near a trash can to absorb certain unpleasant odors.
In the kitchen, this combination can thus become a practical alternative for a few common maintenance tasks. It can notably help refresh the interior of an appliance, limit the odors of food waste, or clean utensils that have accumulated residues. On the hands, the slightly exfoliating side of the coffee grounds also allows you to rub the skin after preparing certain odorous foods, before proceeding with a standard wash with soap. Its main advantage remains its simplicity: the two ingredients are generally already present in the home.
Precautions to know about cleaning before using this homemade mix
However, this natural solution has its limits and requires a few precautions. The coffee grounds can leave marks on certain light surfaces or on delicate materials. Before using it over a large area, it is advisable to test the mixture in a discreet spot. It should not be considered a disinfectant either: neither coffee nor baking soda replace a suitable solution for effectively eliminating bacteria on surfaces that have been in contact with raw meat or high-risk foods.
Finally, to fully benefit from this trick, a few simple rules should be followed. The used grounds for absorbing odors must be completely dry, as moisture can promote mold growth. In a refrigerator or a trash can, the mixture should also be refreshed regularly, generally every one to two weeks depending on odor intensity. Easy to prepare and economical, the pairing of coffee and baking soda illustrates a growing trend: a smarter household where everyday ingredients can find a new function before being definitively discarded.
