I use a dry erase marker. Most of the windows I mark are so filthy, you can barely see if they are fogged and I was tired of people calling me wanting to know which windows were fogged or damaged. Window locations can be hard to show in pics as well. If they let the windows get that dirty, they have no business getting mad about my little blue x. I think I would tell them to wipe it off themselves if they did not like it. Same with outlets.

I think people that get upset with these things are rare and probably the type that would not have many defects to mark anyway as they are meticulous in the upkeep of their homes. Or on the flip side, someone that is miffed about your findings and wanting to give you a hard time. Have not ever had anyone complain about marking, but have had countless calls wanting to know where something was before I started marking them. It is not unusual to have 5 to 10 windows or outlets that are in need of repair and I do not want to try and describe every one of them and include that many pics in my report.
