Window tracks — the channels at the bottom of sliding windows and the sill area around double-hung windows — collect dirt, dust, dead insects, and mould at a remarkable rate. They're also rarely cleaned because the buildup is out of direct sight and hard to reach with standard cleaning tools. Here's the method that works quickly.
What You'll Need
- A stiff-bristle toothbrush or small cleaning brush
- A vacuum with crevice attachment
- Butter knife or flat tool
- Paper towels or old cloths
- All-purpose cleaner or diluted white vinegar
The Method
- Vacuum first — use the crevice attachment to remove loose dirt, dust, and debris from the track. This is the step most people skip; trying to wipe the track without vacuuming first just smears the dirt around.
- Spray the track — apply all-purpose cleaner or vinegar solution to the track and let it dwell for 2–3 minutes to soften built-up residue.
- Scrub with the toothbrush — scrub the corners and the channel of the track where grime accumulates.
- Wrap a paper towel around a butter knife — press it into the track channel and run it along the length. This gets into the corners that a cloth can't reach. Replace the paper towel as it gets dirty and repeat until the track is clean.
- Wipe with a damp cloth — final wipe to remove any remaining cleaner residue.
For Mouldy Window Tracks
Window tracks at the base of windows are common mould locations because they collect condensation. Use diluted bleach solution (1 tablespoon bleach per cup of water) instead of all-purpose cleaner. Apply, let dwell for 5 minutes, scrub with the toothbrush, and rinse. Dry the track thoroughly afterward — leaving it wet contributes to the same mould growing back.
How Often to Clean Window Tracks
- Spring and fall: full clean of all window tracks
- Monthly: quick vacuum and wipe during regular cleaning
