Review on 🧹 Stainless Steel Cleaning Brush for Jardin Aquarium Water Filter Pipe Air Tube Hose by William Bradford

First of all I would like to point out that I did not buy this cleaning brush to clean aquarium pipes. I needed a brush with a long, flexible handle and stiff bristles that could clean the small mold stains that sometimes appear in my humidifier. Unfortunately, this brush is not suitable for this. The bristles on it are so soft they don't actually clean anything, just glide over the areas I was hoping to scrub. The cord/handle also felt more like a spring than what I was looking for - I needed a handle that could flex and hold its shape while using the brush. The cord is very flexible when you apply direct pressure, but returns to its original shape once you stop pressing. I can see where this works for cleaning a narrow U-shaped tube where the tube walls dictate the only path the cable can travel, but even so, the brush's bristles are so soft I doubt it will clean most can the tube walls. I bought this brush based on its good reviews, so I suspect it will work for something other than what I wanted. Note, however, that without direct pressure the cable will not hold its shape and the bristles (the white ones at least) are soft and not stiff.
