Before you start
Check that you can reach the track from inside without removing a heavy sash or leaning out. Read the window maker’s cleaning instructions if you know the model. Work with a dry brush first so water does not turn grit into a paste in the groove.
Tools and materials
- Soft brush
- Vacuum with crevice attachment
- Damp cloth
- Dry cloth
Step-by-step instructions
Open the window from indoors
Move the sash enough to reach the track while keeping both feet on the floor.
Loosen dry grit
Brush dirt towards an accessible corner, then vacuum it away.
Wipe along the groove
Use a well-wrung cloth to lift the dirt the vacuum left behind. Fold it over the edge of a finger for narrow spots and switch to a clean fold as it darkens. Keep water and debris clear of any drainage openings.
Dry and test
Wipe the groove dry, then open and close the window to check how it slides.
Check the result
Run the window through its normal travel and check that the latch closes. Look for loose grit left behind the stops and check the track is dry. If it still scrapes at the same point, note where it happens before trying another clean.
Troubleshooting
If the sash still sticks after cleaning, check for a visible obstruction or worn runner before forcing it.
