Here are 5 frequently asked questions for the AEROWIPE 70% Isopropyl Alcohol Hard Surface Wipes (Tub/100, SKU: AW7700), compiled from clinical and industrial product enquiries.

1. Can these wipes be used on skin or for cleaning cuts?

No. These wipes are strictly formulated for hard, non-porous surfaces. They contain a high concentration of Isopropyl Alcohol ($70\%$ V/V) designed to destroy surface bacteria. Using them on the skin or open wounds can cause severe dryness, irritation, or chemical burns.

2. Do I need to clean a surface before using the wipe?

Yes, for best results. To achieve true disinfection, surfaces should be pre-cleaned to remove visible dirt, dust, or grease. Heavy grime acts as a physical barrier; clearing it away first allows the alcohol solution to directly target and eliminate microbial contaminants.

3. What types of surfaces are safe to clean with these wipes?

They are ideal for hard, non-porous materials.

• Safe to use on: Stainless steel benches, clinic trolley tops, office desks, keyboards, handles, and sealed plastic equipment surfaces.

• Avoid using on: Acrylics, varnished wood, or delicate lens coatings, as the $70\%$ alcohol concentration can cause clouding, cracking, or stripping over time.

4. What is the size of each individual wipe?

These are extra-large clinical-grade wipes. Each sheet measures 42 cm x 14.5 cm. The generous surface area means you can cover large areas—like a full workstation, counter, or treatment chair—with a single wipe, reducing overall waste.

5. How long does the surface need to stay wet to be disinfected?

For effective bactericidal action, ensure the surface remains visibly wet with the solution and is allowed to air dry completely. Do not wipe the solution off with a dry cloth immediately after application; the alcohol needs brief contact time to successfully break down the cell walls of bacteria.
