Some Easy Tips to Maintain Your Windows and Doors Properly

Glass

Always clean the glass using a glass cleaner and a soft cloth to avoid getting scratches on the surface.

Handles

Clean out the dirt and debris from all moving parts on a yearly basis. Lightly oil the moving parts with machine oil. Avoid the use of metal polish or other harsh cleaning products.

Outer Frame & Sash

Clean the surfaces of the frame with a soft cloth to remove grime and dust. Use a mild liquid detergent and rinse with water to remove stubborn stains.

All Lock Types

The key-way, latch and keeps should be kept dirt, debris and obstruction free.

Multi-Point Locks

Apply a generous smear of petroleum jelly or grease to both sides of each additional hook and bolt. This keeps the lock functioning smoothly.

Track

The track surface should be cleaned, and lightly greased, once a year with petroleum jelly.
