New Car Polish Promises Month-Long Dirt Repellency

New Car Polish Promises Month-Long Dirt Repellency: DE-WASH Matte Polish Tested. A new car cleaning product, DE-WASH matte polish, is making waves with its claim of month-long dirt and dust protection. A recent video demonstration shows a noticeable difference between a treated and untreated car panel. "The treated side is noticeably cleaner," says a viewer. The video, however, is an advertisement, so independent verification is needed. Experts recommend caution when relying solely on promotional materials. Further testing is necessary to confirm the product's long-term effectiveness. Until then, consumers should proceed with caution and consider other factors before purchasing.
