Three types of antiseptic wipe

Details are from each product's Drug Facts label on DailyMed. The BZK towelette lists only water and sodium bicarbonate as inactive ingredients, so it is alcohol-free. The alcohol pad is flammable, so keep it away from fire or flame.

How to use an antiseptic wipe

• Open and wipe. The BZK label says tear open the packet, unfold, clean the affected area, and discard after a single use.
• Do not reuse. Labels describe these as single-use; the McKesson box says do not reuse.
• Keep out of eyes. Do not use in the eyes, and do not apply over large areas of the body.
• Sterile packets. The McKesson towelettes are labeled sterile in an unopened, undamaged inner package, so do not use a torn packet.

For a dirty cut, Mayo Clinic says to rinse the wound under running water and wash around it with soap, keeping soap out of the wound. The BZK label's direction is simply to clean the affected area, which makes a wipe handy for the skin around a minor wound when you are away from a sink.

Which one to choose

• BZK towelettes are alcohol-free and labeled as a first aid antiseptic, a common choice for first aid kits.
• Alcohol prep pads are labeled for skin preparation before an injection and as a first aid antiseptic for minor cuts, scrapes and burns. The CURAD label says to protect them from freezing and avoid excessive heat, and not to use them with electrocautery procedures.
• Povidone-iodine pads are labeled for preparing the skin. Mayo Clinic advises against putting iodine in wounds because it can irritate them.

For bottles of alcohol and peroxide rather than wipes, see our rubbing alcohol guide and hydrogen peroxide guide.

Antiseptic wipes are not surface wipes

Searches for antiseptic wipes also turn up household disinfecting wipes for counters and doorknobs. Those are cleaning products for surfaces, not first aid antiseptics for skin. A skin antiseptic has a Drug Facts panel listing an active ingredient and a first aid or skin preparation use, like the labels above. Hand sanitizing wipes are another category; see our hand sanitizer guide for the CDC's advice on alcohol content.

Warnings and limits

• Serious wounds: consult a doctor for deep or puncture wounds, animal bites or serious burns, as the BZK and alcohol labels say.
• Time limit: do not use longer than 1 week unless directed by a doctor.
• Irritation: the alcohol pad label says stop and ask a doctor if irritation and redness develop or the condition persists more than 72 hours; the iodine pad label says discontinue if irritation and redness develop.
• Children: keep out of reach of children, and contact a Poison Control Center if a wipe or its liquid is swallowed.
• BZK towelette: do not insert into the vagina.

After cleaning

Once the area is clean, Mayo Clinic suggests a thin layer of antibiotic ointment or petroleum jelly and a covering for wounds that need one; see our antibiotic ointment guide and adhesive bandages guide. Change the covering at least once a day or when it gets wet or dirty. See a health care professional for signs of infection such as expanding redness, increasing pain, drainage, warmth or swelling. The Red Cross includes 5 antiseptic wipe packets in its first aid kit list.
