Factors influencing the area output of pre-saturated disposable wipes for cleaning and disinfecting surfaces in the healthcare setting

Background: Due to their easy application, single-use surface disinfection wipes pre-soaked in a disinfection solution are very popular. In addition to a broad material compatibility and good antimicrobial activity, it is particularly their area output (reach) that plays an important role. The study’s objective therefore was to determine the area output of commercially available pre-saturated single-use wipes for surface disinfection.


Methods: For the study, six alcohol-based and seven alcohol-free single-use wipes were each used by two persons for three days. The test area consisted of three tables separated into identical sections (six fields). The study participants folded the wipe once to wipe a centre row and then, in circling movements, the remaining surface. As soon as the wipe could not wet the test area any more, the reach was measured and calculated. Additionally, the wipes’ materials were determined and their size measured (folded once = wipe size). Schweins et al. also investigated the wipes’ grammage (g/m2) upon delivery and after rinsing and drying. The difference between these two grammages was the saturation volume.


Results: The area outputs of the alcohol-based disposable wipes was between 0.16 and 0.83 m2. Wipes with a similar wipe size partly yielded area outputs that differed greatly. For example, there were two wipes with a size of 0.016 m2 that had an area output of 0.29 m2 and 0.52 m2, respectively. The reach of single-use wipes made of similar materials increased with grammage and saturation volume. A wipe made of polyester fibres had a higher area output (0.52 m2) than a wipe based on cellulose (0.29 m2). The alcohol-free wipes achieved an area output that is approx. 70 % higher than the one achieved by alcohol-based wipes. Their reach was between 0.12 m2 und 1.64 m2.


Conclusions: The authors emphasise that it is not only the wipe’s size that determines the area output of single-use surface disinfection wipes. In fact, the area output is the sum of different wipe properties: active ingredient, wipe material, absolute liquid content and wipe size. According to this, alcohol-based and alcohol-free wipes made of polyester fleece and with a high liquid content have the highest area output.
