Isopropyl alcohol (rubbing) vs Ethyl alcohol (ethanol/drinking alcohol).
Found this online ... it's Google's AI and doesn't directly credit a source, so I'll just paste it verbatim:
===========================
For removing odors, ethyl alcohol (ethanol) is generally considered better than isopropyl alcohol. While both work primarily by killing odor-causing bacteria and evaporating quickly, ethyl alcohol (specifically in forms like inexpensive vodka) is more effective at breaking down the organic enzymes and compounds that cause smells.
Here's a breakdown:
Mechanism of Action: Both alcohols eliminate odors by denaturing proteins and rupturing the cell membranes of odor-causing bacteria, effectively killing them rather than just masking the smell.
Effectiveness: Ethyl alcohol is often cited as being more effective at deodorizing various surfaces and fabrics. Isopropyl alcohol is also effective, but may not break down the odor-causing substances as thoroughly.
Residue and Scent: Ethyl alcohol, especially in high-purity forms or as vodka, evaporates quickly and leaves virtually no residual odor or residue behind. Isopropyl alcohol has a more distinct, pungent chemical-like odor that can sometimes linger, though it generally fades as well.
Fabric/Surface Safety: Ethyl alcohol is considered gentler on many fabrics and less likely to cause damage or discoloration compared to isopropyl alcohol, which can potentially damage certain materials like silk, wool, rayon, or some painted surfaces.

I guess I'll do some tests at home, and potentially go vodka shopping on the next trip!
