Is full strength bleach solution not effective as a desinfectant?

Full strength is less effective than a 10 to 1 solution. It has been a while since I was trained on that but it had something to do with the ease of the diluted solution penetrating the viral cells.

@Subsumedpat its a surprise that the diluted solution is more potent!!
