Application techniques for Biocleanse™ on visually sensitive surfaces
Background
Biocleanse™ can be applied by several techniques
- Spray and wipe using a trigger spray
- Wet wipe pre-impregnated with Biocleanse™
- Immersion in Biocleanse™ solution with or without ultrasonic agitation
An important contribution of Biocleanse™ to infection control is its residual activity on surfaces. This requires active matter to remain on a surface between cleans. Some combinations of technique and substrate result in a visible residue that is considered unsightly, particularly on glossy finishes with dark colours.
Discussion
For most surfaces with low gloss, disinfecting by spray and wipe or wet wipe will leave a visually acceptable finish. On high gloss surfaces, particularly those with dark colours, small amounts of residual product can produce a visible residue. This is especially apparent to customers who have historically used alcohol sprays or wipes as these products have zero residues. Obviously, a zero residue product cannot offer residual activity.
Wet wipes leave a greater volume of residual product than spraying and wiping since the wipe is saturated and cannot simultaneously deposit liquid on the surface and re-absorb that liquid. Using a trigger spray with a dry tissue wipe ensures effective cleaning and disinfection with lower residues as the dry tissue is able to absorb the used disinfectant more completely. The active ingredient in Biocleanse™ is substantive to surfaces so a microscopic layer will remain and provide lasting activity.
Conclusions
- The recommended procedure to follow on visually sensitive surfaces is to use Biocleanse™ in trigger spray format and wipe with absorbent tissue to remove excess product.
- Residual activity alone should not be relied upon for infection control. All surfaces in areas where pathogens could be present must be cleaned and disinfected on a frequent basis. The required frequency depends on the level of risk but will generally not be less than once per day.
