The sash stops must be removed, a thin vertical strip of wood that holds the sash. Also, remove any hardware that has been painted. Pull the sash back to reveal the weight. It is a heavy iron or lead cylinder, which is tucked away in a cavity, and supported by an elastic cord. To prevent the sash falling into the void, pierce it with a nail and then let the weight go.
After the sashes have been removed clean the jambs and rails that connect them. Remove the glazing bars and the sash cords. Then, using a utility blade take off any paint that is on the sash stop.
