Review on 🔧 Ultimate Cleaning Tool: Drill Brush for Motorcycles, Cars, Trucks & More – Tackle Wheels, Rims, Tires, Saddle Bags, Windshields, Glass, Leather, and Vinyl with Ease! by Michael Zambrano

Fairly effective for my glass shower door but not quite satisfied yet. Water stains on the top of the door removed very well, but more stubborn stains on the bottom of the door containing soap/shampoo/conditioner residue did not remove well. Even when the brush is rotated on the door, it's cool, like it's "jumping", not like we'd like, it gently clings to the glass. I guess if we replace the hard brush with a hard sponge it might work better because we can press it firmly against the glass door without "bouncing back".
