FAQs

What concentration of alcohol do these swabs contain and why does it matter?
+

Aerowipe Alcohol Swabs contain 70% isopropyl alcohol — the concentration that is most widely specified for clinical skin antisepsis. It might seem that a higher concentration, such as 99%, would be more effective, but the opposite is true in practice. Pure or very high-concentration alcohol evaporates too rapidly to allow sufficient contact time with the skin surface to kill bacteria effectively. The 30% water in a 70% solution slows evaporation, prolonging the contact time and improving penetration into bacterial cell walls, producing a significantly better antimicrobial result. The 70% concentration is the clinical standard used across NHS and healthcare settings worldwide for injection site preparation and skin antisepsis.

Do I need to use an alcohol swab before a finger-prick blood glucose test?
+

Current UK diabetes management guidelines generally advise that for routine home blood glucose testing, washing the hands thoroughly with soap and warm water and drying them completely is sufficient preparation and preferable to alcohol swabbing. Using an alcohol swab before a finger-prick is not routinely recommended for home glucose testing because any residual alcohol can affect the accuracy of the reading and because regular alcohol swabbing can dry out and harden fingertip skin over time. Alcohol swabs remain appropriate for injection site preparation before insulin or other subcutaneous injections. For specific guidance on your personal blood glucose testing procedure, follow the advice of your diabetes specialist nurse or GP.

Why must I wait for the skin to dry before injecting?
+

Injecting through wet alcohol causes a sharp stinging sensation that is entirely avoidable by allowing the alcohol to dry first — typically 15 to 30 seconds at room temperature. There is also a theoretical concern that alcohol introduced into subcutaneous tissue by the needle could affect the local tissue environment, though this is clinically minor in practice. Waiting for the skin to dry is a straightforward step that makes the injection more comfortable without adding meaningful time to the process. In clinical settings, 30 seconds is the standard wait time after alcohol skin preparation before proceeding with any injection or skin puncture procedure.

Can I use these to disinfect blood glucose monitors or other home testing equipment?
+

Alcohol swabs are frequently used for surface disinfection of home testing equipment including blood glucose monitors, lancet devices, and other reusable clinical tools. Wipe the surface with the swab and allow to air dry completely before the device comes into contact with the patient. However, not all materials are compatible with isopropyl alcohol — check the manufacturer's instructions for your specific device before using alcohol swabs on it, as some sensor components, display screens, or rubber seals may be damaged by regular alcohol contact. For the lancing device platform specifically, follow the instructions provided with your device.

Are alcohol swabs flammable and how should I store them safely?
+

Yes. Isopropyl alcohol is flammable, and while the alcohol is sealed within individual wrappers and the risk in normal use and storage is low, the product should be stored away from open flames, heat sources, and direct sunlight. In a clinical or workplace setting, do not store large quantities adjacent to electrical equipment that generates heat or in direct sunlight through a window. When using alcohol swabs for skin preparation, ensure the treated area is completely dry before any procedure involving electrosurgery, diathermy, or any ignition source. In normal first aid and home use, the flammability risk is minimal provided the basic storage and handling precautions are followed.

How long does an individual swab remain effective once the wrapper is opened?
+

Once the individual foil wrapper is opened, isopropyl alcohol begins to evaporate rapidly — within a minute or two at room temperature in open air, the swab can lose a significant proportion of its alcohol content. This is why alcohol swabs should always be opened immediately before use rather than prepared in advance. An opened swab that has been left for several minutes is unlikely to provide reliable antiseptic activity. Always open the wrapper at the point of use, apply immediately, and discard the swab after a single use.
