This pro version versus power safe versus grout ? I'm going blind trying to compare the smells and dilutions myself. grout smart says it's got a natural orange odor to it, what about the other two?

Question 37

I am sampling one AC vent in my home. The vent grills have what appears to be dark mold on them. I would like to take a sample from the surface of the grills (visual mold) and also attach the petri dish to the same vent. Can I put the surface mold on 1/2 the petri dish and leave the other half empty when I attach the petri dish to the AC vent. If I need to use 2 tests, one for the air flow coming out of the AC vent (attach to the AC vent) and one for the surface mold, is it ok to swipe the surface of both the grills and the inner wall of the same AC vent. I didn't know if I need 2 test kits for sampling the AC grills and the vent wall on the inside of the AC grills. It is black with suspected mold growth too, unless it is just dust. View answer
