Remove all dust and grit before lubricating pivot points, and all other moving metal parts with light machine oil. This should be done annually.
Light application of petroleum jelly or an equivalent will keep locking mechanisms and hinges in good working condition. A resin-free grease or lubricant should be used on sliding bars, gears, and faceplates. With sliders or single hung windows, a silicone spray (candle wax / furniture polish) can be used to lubricate the sashes to help them slide smoothly. With double hung windows, a few drops of light machine oil or spray such as WD-40, applied via the top end of the balance tube, will improve the operation of the balance.
Other maintenance tips for hardware & screens:
- Follow exterior surface cleaning instructions for all exterior screens.
- Interior mounted screens can be vacuumed with a soft brush attachment, or wiped with a soap water solution.
- The easiest way to clean screens are to remove them, and lay them on a flat surface.
- Apply cleaning solution to the screens and let them soak for a minute. Then, rinse the screens using a low-pressure spray. Alternatively, you can vacuum them with a soft brush.
We would like to stress that extra care should be taken not to overreach or risk falling!
