Jackie I head right for the bathroom after company leaves...we have a white marble floor...my husband's family is his dad and two brothers. Then we have a great grandson, Connor. Dried Urine on the floor by the toilet, with dirty footprints in it is not uncommon. Out come the paper towels, Clorox, water, kneepad and I'm on my way...only takes a couple minutes to clean it up. I also clean the toilet bowl and rim.
We do not have a dishwasher, so I scrub the silverware and dishes with HOT, HOT, HOT sudsy water, and scrub the counters clean.
I babysat Connor at his apartment several weeks ago. He had a runny nose and kept wiping it on his hands, clothes, then grabbed my hand. I was sick two days later even though I really tried to keep wiping his hands and giving him Kleenex. I gave a speech on germs when I was in the Toastmasters public speaking club. You are NOT weird! I consider myself to be a germ-a-phobic. Great question!
