As someone with a little touch of OCD, I find that I feel stressed when cleaning my bathroom because I worry about cross contamination. When I finish cleaning one part of the bathroom floor, and then clean the other part, if I end up needing to touch something I've either already cleaned or a cleaning product, I tend to wash my hands before doing so.
For example, while cleaning the toilet, I feel the need to wash my hands before grabbing the spray bottle, as I'm concerned that there may be cross contamination between the spray bottle and the toilet. Overall, I tend to take cleaning the bathroom in the same light as if I were in a Nuclear Bio Chemical attack zone.
I know it's not the same. Unlike NBC (Nuclear Biological Chemical), cross contamination isn't (and hasn't) killed me yet, but I wonder, what is the general rule of thumb for hand washing while cleaning the bathroom.
Should we hand wash after cleaning each fixture, wait until the end, or is there some other procedure? What research is out there on this topic? I tried googling the title of the question "How often should I wash my hands when cleaning the bathroom?" and nothing came up; hence, I ask here.
