Special knowledge is necessary to handle bio-hazardous material in an appropriate manner and also to know what exactly to look for at a crime or biohazard scene. The cleaning company also needs permit to transport and dispose of bio-hazardous waste. We at Bio-Cleanse Pty Ltd have all of the necessary permits, training, expertise and most important, the willingness to handle gross filthy things that would send most of us running out the door to throw up in the bushes.
