As it is a functional wiper made out of 100% silicon, please keep these tips in mind if you wish to enjoy the optimum performance:

• Be careful not to drop the wiper arm when replacing it, as the fall may crack the windscreen.
• Wear gloves when replacing the wiper to prevent injuries.
• Use a soft cloth to remove hardened foreign substances, such as a sticker, resin, bird feces, or sharp frost, instead of using the wiper.
• Using the wiper to remove them may scratch the silicon blade, causing it to have stripes.
• Do not apply water-repellent coating substances (wax, water-repellent coating washer fluids, and others), chemicals, films, etc., on the glass.
• Doing this may cause the wiper to create noise or rattling sounds.
• Clear off dust or sand granules accumulated upon the blade with wet tissues or a soft cloth when the wiping performance gets considerably weakened. If such an action does not have considerable effect, operate the wiper to apply automatic water-repellent coating substances.
