Answer: cleaning and lubricating non-static parts, vacuuming in the grooves and applying wax.
Sliding doors are ideal if you want to save space. They can be fixed on a rail on the floor or on the ceiling. If the floor system is rather easy to install, it wears out over time, notably due to the fouling of the rails. So prefer hanging sliding doors to facilitate their opening. Not only does the ceiling rail support heavier loads but it also saves space. Maintain rails regularly to improve door opening, cleaning and lubricating non-static parts. Also check the tightness of the screws and dust the slide rails. To do this, vacuum the grooves, remove the residue with a damp sponge and apply a little wax to the exposed part of the rail. Your doors will slide much better. You too, send us your brico question
