Detailers weigh in on using Costco's microfiber towels for car paint

Costco's Kirkland Signature microfiber towels are debated by detailers for car paint use due to their 80/20 blend and 350 GSM density. While versatile for general cleaning, the blend and density may cause micro-scratches on delicate paint compared to higher-polyamide, plusher towels. Stitched edges also remain a concern. Detailers suggest using them on paint with ample lubrication and light pressure, or reserving them for less critical tasks like wheels and glass.
