Why does vinegar clean glass well?
Show answer & explanation
Answer: Acid dissolves mineral deposits
Vinegar is perfectly clear liquid — Wrong. Being clear doesn't make something a good cleaner. Vinegar works because of its chemical properties, not its appearance.
Vinegar smells keep dirt away — Wrong. The smell is just a side effect of acetic acid. Vinegar cleans through chemical reaction, not by repelling dirt.
Acid dissolves mineral deposits ✓ — Correct! Vinegar contains acetic acid, which dissolves hard water stains and mineral deposits (like calcium carbonate) on glass. The acid reacts with alkaline residues, breaking them down. That's why it leaves glass streak-free and sparkling!
