I've been seeing tons of videos lately where people mix vinegar and baking soda to clean their shower tiles and drains, and it looks impressive with all the fizzing. But I'm curious what's actually happening chemically when you mix those two together. Is the fizzing doing the actual cleaning, or is it just for show?
I've tested this on stubborn soap scum before and the fizzing definitely helps - it physically lifts gunk out of crevices and off surfaces as those CO2 bubbles form, so it's not purely visual. The actual cleaning power comes from the acetic acid in vinegar breaking down mineral deposits and soap buildup, while the baking soda acts as a mild abrasive, so you're getting two different mechanisms working together rather than one doing all the work.
Here's what most videos skip: pour the baking soda into the drain or on the tiles first, then add vinegar slowly and let it sit for 15-20 minutes before scrubbing. The immediate fizz looks cool but it dissipates fast - giving it time to work means the acid has longer to dissolve buildup instead of just bubbling away in seconds.
When you mix vinegar (acetic acid) and baking soda (sodium bicarbonate), they react to create carbon dioxide gas, water, and sodium acetate - that's what causes the fizzing. The fizz itself isn't really doing the heavy lifting for cleaning; what matters is that the vinegar is mildly acidic so it breaks down mineral deposits and soap scum, while baking soda acts as a mild abrasive that scrubs surfaces when you physically work it in. The fizzing action can help dislodge loose debris in drains and crevices, which is legitimately useful, but the actual cleaning power comes from those chemical properties working on the grime, not from the bubbling itself. So yeah, the videos look satisfying and it's a real cleaning method, but the dramatic fizz is more theater than the actual mechanism doing the work.
the fizzing is doing real work but honestly not for the reason people think - those bubbles lift debris mechanically, yeah, but the actual cleaning power comes from the vinegar itself, which is an acid that breaks down mineral deposits and soap scum way better than baking soda alone. what most videos don't mention is that once they stop fizzing (usually within a minute), you've already lost the chemical reaction, so if you let it sit for 20 minutes like some creators suggest, you're basically just leaving vinegar on the surface. here's what actually works: spray the area with straight vinegar first, let it sit for 10-15 minutes to soften the gunk, then sprinkle baking soda and scrub immediately while the fizzing happens - that's when the bubbles do their job alongside the already-softened deposits. way more effective than the tiktok approach of watching it bubble for Instagram points.
