How to apply grease
Take a small amount of grease in your hand and apply it to the jagged parts of the open zipper, spreading it evenly over the entire zipper.
Regular maintenance
If sand, dust, or other dirt remains on the zipper, it will prevent it from opening and closing smoothly. Also, the grease will evaporate and gradually lose its effectiveness.
To keep the zippers opening and closing smoothly, we recommend cleaning them and applying grease regularly.
