Interesting fact about wood!
New studies have shown that the germicidal effect is most pronounced in pinewood. The number of bacteria is not only reduced, but goes back in the interior equally.
Even with repeated bacterial entry, the antibacterial effect is retained. On the other hand, the survival capacity of bacteria on plastic (polyethylene) is greater than on wooden material. A noticeable reduction in germ counts begins after 12 to 24 hours. Repeated germination even leads to an accumulation of viable bacteria. Cleaning and disinfection of the plastic surfaces only provide a short-term relief. The causes of the antibacterial effect of wood lie in its hygroscopic property as well as the constituents. – www.wilms.com
