Take out the sash stops, a thin vertical wood strip that holds the sash. Also, take off any hardware that has been painted. Pull the sash to reveal the balancing weight that is a massive iron cylinder or lead that is enclosed in a hidden cavity and secured by a rope. To prevent the sash falling into the void, pierce it using a nail, and then let the weight go.
When the sashes are untied clean the jamb and rails that meet, remove the glazing bars and sash cords, and scrape off any paint from the sash stops using a utility knife. After the sashes have been put back in place, you can reattach the stops using nails that are small enough to avoid puncturing the balancing weight.
