Overview

• Argentine media widely share a standardized lemon‑peel and bicarbonate paste as a low‑cost multiuse cleaner, often citing a recipe of 2 lemon peels, 1/2 cup water and 2 tablespoons of baking soda blended into a paste.
• Recent guides elevate powdered citric acid as the preferred descaler for stubborn mineral buildup, advising 2–3 tablespoons dissolved in hot water and an overnight soak for toilets and fixtures.
• Coverage extends the approach to other residues, recommending potato peels with bicarbonate to loosen rust, avocado peels as a gentle scrubber for kitchen surfaces and odors, and crushed eggshells with bicarbonate as an abrasive for cookware.
• Hygiene tips feature prominently, including Lucía Lipperheide’s advice to wash toothbrush cups weekly with hot water and vinegar and to place antiseptic‑soaked gauze inside to curb odor and residue.
• Articles stress precautions such as washing peels to remove pesticides, testing mixes on small areas, avoiding ad‑hoc product combinations and not using these preparations as medical treatments despite some reported consumption claims.
