U.S. Pool SupplyHand-Held Pool Scrub Brush, 2 Pack - Scrubbing Scouring Sponge Pad - Clean Pool Tile & Grout, Walls, Vinyl Liners, Spas - Surface Cleaning Scrubber, Kitchen, Bathroom Tub, Shower Tile

I supported our family during seminary by starting a window washing business. One of my tools was a similar looking but much softer scrub brush which I could purchase in several stores. I could not find them so thought I would try these. They are pretty stiff, but they do actually work and they do not scratch the glass. (Spray on Glass Plus, wipe around window with pad, squeegee off and clean up with a paper towel.) Works for me.

These worked great with my inflatable hot tub. With a small amount of cleaner they quickly loosened grime from the water line. Quality appears very good.

Best for scrubbing tub and shower

This hand-held scrub sponge did a great job on my tiled water line. It's good value as well. The problem was when I started brushing the gunite surfaces lightly. I didn't notice it at first but the sponge was disintegrating and left hundreds of white fluffy pieces throughout the pool. The moral of the story is that it's great for flat surfaces but I wouldn't recommend it to be used on anything textured.

Very easy to use (Naturally). Keeps tile of pool clean… use once a month.

I use the scour brush to remove calcium scale on the pool tile with muratic acid

They work well but wear out fairly quickly.

Work great for scrubbing little bugs off upper tiles on our inground pool - would order again.
