Use your own judgment re. cleaning the carpet & furniture. My son had C. diff. twice many years ago before it was known you could "catch" C. diff. from another person, & no one else in the family got it. I had C. diff. twice many years later, & no one else in the family did. Again, not much was known about its "catchiness."
Concentrate cleaning the bathrooms & the places on the rug. The bleach solution is l part bleach to 9 parts water. I'd also check with your mother's doctors re. cleaning.
Again, so sorry about your mother. Pls. educate others about this horrible illness. It is too late for your mother, but might help you as you grieve over the loss of your mother. And do have everyone make a special effort to wash their hands before & after visiting your father.
