Review on 🧹 Optimized OXO Good Grips Deep Cleaning Brush Set (3 Pack) by Melissa Dufour

I didn't particularly like these brushes but I'm looking for new ways to clean more effectively AND more efficiently while preserving my expensive 20 year old finishes. I use them for spot cleaning, in the natural crevices of my travertine, smoother Italian tile, and with specialty cleaners around drains and jets (in my marble shower and tub) for that nasty limescale build-up known in Tuck Texas. Thank you for specialized, durable, but quite gentle products.
