I have an outlet in my room that is only hot when I flip a switch on the wall. I have been in places before where the switch only controls the bottom half of the outlet and the top is hot constantly. Is there a way I could do this to my current outlet?
Not if there are only two wires coming into the box, one wire attached to each side of the receptacle (outlet) unit.
When cleaning anything including baby diapers, it is better to sweep off or scrape off as much solid and semisolid material as you can first. (1) Less cleaning fluid or detergent needs to be used, (2) Less of a mushy mess which in turn means that bleaches or disinfectants will be more effective.
