I have 12-year-old Peachtree Ariel non-tilt double-hung windows whose counterbalance mechanisms have become stiff. One actually failed, which led me to disassemble the window to understand how they work and what had happened. They are basically block-and-tackle (I think that’s the term) arrangements with a rather thin cord running over and around a series of plastic pulleys and then to a short, strong spring. The one that failed did so, apparently, because one of the little pulleys broke. I’m selling the house and would like to do some preventive maintenance that I imagine would consist of applying some sort of lubricant to ease the binding I now feel when I raise or lower the windows. Does anyone have any related experience or suggestions as to the appropriate lubricant? Thanks!

Triflow spray lube. If your hardware store doesn't have it check with a bike shop. It contains microscopic teflon beads and will have a sticky mechanism working smoothly in no time, without leaving an oily film.
Don't use WD40. It may briefly improve things but quickly evaporates. Plus it can damage the plastic parts.
