Brazilian homes turn used yerba mate into a baking‑soda cleaning paste

In Brazil, a growing number of households are repurposing used yerba‑mate leaves by mixing them with baking soda. The dried leaves provide a gentle abrasive texture, while sodium bicarbonate absorbs odors and cuts grease. The blend is promoted as an inexpensive, eco‑friendly alternative for light cleaning tasks and odor control in refrigerators, trash bins, shoe racks, cabinets, stainless‑steel surfaces, and mild grease removal.

Preparation involves fully drying the used leaves, then combining one or two tablespoons of baking soda per cup of leaf material and storing the mixture in an airtight container. Users are warned to avoid delicate finishes, as the mild abrasiveness can scratch sensitive wood or metal. Moisture must be eliminated to prevent mold or unpleasant smells during storage. The practice reflects a broader push toward waste reduction and sustainable household habits.
