Window tracks collect dust, insects, grit, and mud that can impede movement and hold moisture. Effective cleaning starts dry: vacuum loose debris, loosen deposits with a narrow brush, then use a small amount of soapy water. Do not block weep holes or turn the track into a trough full of liquid.
Vacuum before adding moisture
Open the window enough for access without forcing it and vacuum corners with a crevice tool. Wetting first turns dust into mud and pushes particles toward rollers and drains.
Brush corners and channels with a narrow tool
An old toothbrush or small stiff brush can loosen dirt without scratching. Vacuum up what you release rather than pushing it into the end of the frame.
Use minimal water and dry afterward
Wipe with compatible soapy water and follow with a clean cloth. Avoid pouring water directly into the track because it can enter cavities or remain trapped. Use even less moisture around wood frames.
Keep weep holes open
Many frames have small weep openings that let rainwater escape. Clear them with a non-destructive tool without enlarging them. If water still enters indoors with drains clear, investigate seals, slope, or installation rather than just dirt.
