Light switch plates are an excellent place for germs to spread from family member to family member. Take the time to wipe these down with the regular cleaning chores. Spray a general purpose cleaner on a cleaning cloth and wipe. Don’t ever spray the switch plate directly or use too much water since you are close to a power source. For heavy restorative cleaning, I have taken switch plates off the wall, washed them in the dishwasher and then put them back. Door jams are also often over looked for cleaning and they are often touched by people, mostly children going in and out of rooms.
