Bathrooms are a Hot Spot for Bacteria
The humid moist conditions in a bathroom, allow germs, bacteria, fungus and yeast to thrive. Additionally, every time the toilet is flushed, a fine plume deposits contaminated particles onto everything nearby.
Showers, baths and basins in frequent use, create a build-up of hair & skin exfoliates, soap scum, germs & dirt which stick to surfaces and gradually build up. These hard-to-remove surface contaminants can provide an anchorage for bacteria, fungus and yeast to grow, resulting in the growth of black fungus.
The trick is to clean and fog often, so nothing builds up.
AirVisan is a potent sanitizer which keeps on working if left on surfaces, although the speed of germ kill is proven to take seconds.
