Make use of a sharp knife, and place sheets of plastic as well as an air-collecting vacuum cleaner beneath the surface to collect any paint dust or chips.
Clean the tracks with a dry cloth, then apply a silicone-based lubricant that will help them slide better. This lubricant is available at most home improvement shops or on the internet. You can test it by moving the sash either upwards or downwards.

Draughts
Draughts can be a concern with sash windows that are old, especially during the winter.

An alternative that is less expensive is to have your sash windows professionally draught proofed as part of a complete refurbishment service. This could include the replacement of sash cords, parting beads, staff beads, lubrication for the pulley wheels, and rebalancing the weights, as well as staining or painting the frames and sashes.

The next step is to take off the "pocket covers" which are bits of wood in the side of the frame low down that give access to the weights (the parting beads run down the middle of them). These are often put in place by nails and then covered with paint, so you'll likely need to use an instrument to break them off. Once the pockets are gone, you can begin to chisel away any wood that is rotting, and then apply a high-quality water-resistant wood filler. Once the filler is dry, it is recommended that a coat of primer be applied to prevent further decay.
It is a smart idea to examine inside the window the sashweights to ensure they are properly balanced. They should not be displaced or pulled one side harder than the other. The sash could be thrown off its track if they are not properly balanced. This could cause the frame to break or be damaged.
