In short: alcohol (~70% IPA) acts fast and dries clean — ideal for routine injections and venipuncture on intact skin. Povidone-iodine (~10%, ~1% available iodine) has a broad spectrum and longer residual action, often chosen for pre-surgical prep, but works more slowly and can stain. Many buyers stock both. Always follow applicable clinical guidelines.
Quick comparison

| Residual effect | Minimal | Longer-lasting |
| Typical use | Routine injections, venipuncture | Pre-surgical, broader prep |
| Skin / staining | Dries clean | Can stain; may irritate some skin |

Frequently asked questions
Can I use alcohol on open wounds?
Generally not advised — follow clinical guidance. Sterile saline or appropriate antiseptics are used for wounds.
Why does povidone-iodine need to dry?
Its antimicrobial action continues as it dries; wiping it off too early reduces efficacy.
