Review on Versatile 2-in-1 Chenille Microfiber Car Wash Brush Mop Mitt with 45-inch Aluminum Alloy Long Handle – Car Cleaning Kit Brush Duster, Gentle Yet Effective Cleaning Tool to Protect Paint, Scratch-Free Dust Collector Supply for Washing Trucks by Michael Willis

I'm not a car wash noob. Did it for 20 years. This brush head is junk. The problem is that the microfiber scrub is put on a hard plastic head. The rigid plastic head cannot bend or conform to the shape of the surface. So if your laundry isn't perfectly flat on all sides, this brush will skip stains. So I don't know if you plan to wash, for example, a car with curved and rounded doors, trunk and hood. Around the handles and bumpers and side mirrors. It just doesn't work well. I gave it 5-6 rounds just to see if there was anything I could do differently but it just didn't change. It doesn't matter what car I wash, I always end up with a few missed spots that stick out like a thumb. I do not recommend.
