How can you sanitize myself for someone who has cat allergies?

Dander avoidance: Cat dander is light and sticky. It can be in dust, on clothing, carpeting, walls, furniture and airborne (if house dust is disturbed). A thorough house cleaning would include carpet cleaning, swiffer the walls, and an air purifier. For just the person, shower/wash hair and clean clothes would make that person less likely to transfer cat dander to another person.
