Our sliding door factory generally uses professional sliding door wheel and rail grease, which is colorless and transparent, with good adhesion and durability. Hutou hotolube or Krupp can be used. It has food-grade safety certification and is suitable for home use. There are 13 grams of tubules in the trap. When in use, it is directly applied to the slide rail and pulley, and the sliding door can be opened and closed several times.
don't use lubricating oil and ordinary butter on sliding rails and slideways of sliding doors, the lubricating oil will be lost soon. Ordinary butter will have a harmful smell that is not good for human body.
