【More Detailed Repair】
Two grinding surfaces, coarse and fine, and two repair procedures, make the wiper surface smoother. When the wear is serious, first use coarse sand to repair, then use fine sand to polish.
For driving safety, we usually need to replace the wipers within 3-6 months. But for the wiper problem caused by wear, aging, and stains, you can use a wiper repairer to solve it. Save at least two pairs of wipers every year.
The double-sided streamlined design, following the ergonomics, is easier to master and better apply force. Don't think of this as a difficult thing!
【Rotating Card Slot】
When the grinding disc is used up, the slot can be rotated with a dollar coin to move the sanding disc up and down, turning out a new grinding disc, and prolonging the service life of the repair device.
【Cleaning And Maintenance】
After the wiper repair device is used, fine particles will remain in the grinding groove. It can be cleaned with a coarse brush with a hard material (you need to buy it yourself), or you can clean it directly with water. Then wipe clean.
