Sodium bicarbonate (NaHCO3), acetic acid (CH3COOH), and aromatic hydrocarbons…
IS. NOT. A. CHEMICAL. FREE. CLEANING. PRODUCT.
And you’ve watched too many “foaming scrubbing bubbles” commercials. That foaming you see when you pour the vinegar into the baking soda is not cleaning happening. It is an acid and a base reacting to neutralize both, producing a salt.
If you must clean your toilet with baking soda and vinegar, do it this way:
- Pour in baking soda, sprinkling it on the sides of the bowl. It’s a mild abrasive; scrub. It will also neutralize some odor (although this works better with the dry powder as an absorbent in the fridge).
- If you still have tough build-up, flush to get rid of the baking soda solution, then pour in vinegar. Slosh it around, and let it sit for a while. The acid will eat at the build-up. Scrub and flush again.
- Study basic chemistry.
Mixing them together is useless. Stop doing that; you’re wasting your money.
And if you’re doing this to be “green”: Congratulations! You just released more evil, Gaia-heating carbon dioxide into the air. And flushed sodium acetate (an irritant) into the sewer/septic system. Gaia hates you.
