For traditional wood sash windows, the best lubricant is a solid wax, such as a high-quality beeswax or a wood paste wax (e.g., Minwax Paste Finishing Wax). For vinyl or metal sliding sash windows, a silicone-based dry lubricant spray or specialized window/door lubricant spray is ideal. Never use petroleum-based lubricants (like standard WD-40), as they attract dirt and ruin wood and vinyl.
A silicone-based lubricant is typically the best option because it reduces friction without attracting dirt or leaving behind heavy residue. To apply it correctly: Spray the lubricant onto a clean, dry cloth rather than directly onto the window.
To make sashes glide more freely, rub a lubricant into the window tracks; examples include beeswax polish, candle wax, a damp bar of soap, and a silicone spray. At regular intervals, close each window and then re-open it. This will help to ensure the lubricant is spread out evenly.

Solution: Regularly inspect your sashes for signs of wear. If they stick, carefully remove the staff bead and parting beads to clean the edges and re-align the sashes. Applying a lubricant can also help ease movement. If the sash window cord is damaged, it may need replacing to restore proper function.
To make sash windows slide more easily, clean the tracks and channels with a stiff brush and vacuum, apply silicone spray or candle wax to the running channels, check and replace worn sash cords or spiral balances, and ensure the window is not paint-stuck by scoring along the edges with a utility knife.
Popular options would be silicone sprays like WD-40. It's best to stay clear from heavier oils or greases as those could accumulate more dirt and debris over the course of time. If you have new windows then you should have been instructed on how best to maintain your windows; so always follow their recommendations.

To make a sticky sash window slide smoothly, start by thoroughly cleaning the tracks to remove built-up dirt. Never use heavy, petroleum-based lubricants like standard WD-40, as they attract grit that turns into sandpaper. Instead, apply a silicone-based spray or wax lubricant specifically for windows.
DO NOT USE SILICONE SPRAY ON ELECTRICAL CONNECTIONS, SWITCHES, RELAYS, ETC. There have been numerous reports that silicone spray can cause contact problems in switches, noted in multiple posts regarding automotive problems.
To make windows slide easier, thoroughly clean the tracks using a vacuum and a screwdriver, then lubricate the moving parts with a dry film silicone spray or a rub of candle wax. Avoid petroleum-based products like WD-40, as they gum up with dust and make windows stickier over time.

Teflon Dry Lubricant
Teflon-based dry lubricant is preferred by some locksmiths over other options. It's a great option because, as well as lubricating your lock, it repels water and dust. Meaning that once you fix a lock with this type of lubricant, you can expect the lock to be in good shape for a long time.
Silicone Based Lubricant
The lubricant you use to help unstick your windows should be silicone based. Popular silicone based lubricant sprays include WD40 Silicone and 3-In-One Silicone. Unlike oil-based lubricants, silicone lubricants don't attract dirt and can help protect against moisture.
