1. Window Locks
Begin by wiping the window locks with a dry cloth to remove any loose dust. Take a clean cloth and warm water to wipe clean. After this, wipe clean with a damp cloth and dry thoroughly. This can be done very occasionally; however, it would be recommended to be done weekly to keep everything clean and running smoothly. They can also be kept in their best condition by lubricating with a little light 3 in 1 engineering oil.
