Frequently Asked Questions

Can I use WD-40 on sliding door tracks?expand_more
Regular WD-40 can leave a sticky residue that attracts dirt. Use silicone lubricant or dry graphite instead.
How do I remove the sliding door to clean the track?expand_more
Lift the door slightly and tilt the top inward while supporting the weight. It helps to have a helper, but many doors can be lifted solo once rollers are retracted.
Why is my door only sticking at one spot?expand_more
A bent track segment or a damaged roller can cause sticking in a specific place. Inspect that spot closely for dents.
Should I replace the whole track if it's damaged?expand_more
Minor dents can be straightened with a rubber mallet. Only severely bent tracks need replacement.
Will cleaning the track fix a door that is completely off its roller?expand_more
No, you’ll need to lift the door back onto the rail and possibly replace rollers.
