What is the difference between double rubber wiper blades and single rubber wiper blades?

[DeKennedy]

Double rubber wiper blades are better. Here are the specific details: Double rubber wiper blades: The outer scraping edge uses a micro-particle sandblasting coating (for cleaning), while the inner scraping edge uses a lubricating coating (for water removal). With each swing of the wiper, dirt removal and water scraping are completed simultaneously and independently. Therefore, the number of wipes required is far fewer than traditional single-edge wipers. Moreover, thanks to the refined division of labor, the water-scraping edge is well protected, significantly extending the functional lifespan of the blade. Additionally, the cleaning speed is at least 2-2.5 times faster than ordinary single-edge products. Precautions for double rubber wiper blades: Clean the wipers correctly. Avoid exposure to high temperatures and steer clear of ammonia-containing cleaners.
