I use food grade hydrogen peroxide(I think its at 35% concentration) diluted down with water and vinegar in 2 separate spray bottles. I spray with one then spray over it with the other. Then let air dry. I try to avoid bleach and from what I have read this is more powerful a disinfectant than even bleach and not toxic. I use it on sinks, counter tops. cutting board, anything I want to disinfect.
