Overview

• TN.com.ar now recommends sprinkling fine salt on the bowl each night to soften limescale, curb odors and target bacteria between flushes.
• An earlier TN.com.ar piece advises tossing 2–3 tablespoons of baking soda into the toilet once a week, letting it sit for about 20 minutes, then scrubbing and flushing.
• That weekly method can be boosted with a splash of white vinegar to create an effervescent reaction that helps loosen tough residue, according to the guide.
• El Imparcial describes a viral mix of 250 g salt, 250 g baking soda and 25 tablespoons neutral oil spread inside the bowl, left overnight, then finished with boiling water and a flush, with optional lemon juice for scent and shine.
• The publications suggest different cadences for upkeep, from nightly salt to weekly baking soda to monthly or biweekly use of the salt–bicarbonate–oil method, and they present these as low-cost alternatives with minimal explicit safety warnings compared with earlier DIY tutorials.
