Review on 🧼 Versatile Pumice Stone Trio: The Ultimate All-Purpose Solution (3 Pack) by Ebony Brown

I have tried several different pumice stones to remove scale (calcium?) from my pool walls and comments mentioning that they are too soft may not have been tried by others. soft stone and that's part of how it works. Removes limescale without damaging the shotcrete/gypsum surface as pumice is MUCH softer. Try something stronger and you'll take the cast off. This is not the goal. What makes these bars very valuable is their size. I paid almost twice as much for a much smaller pool shop bar. They actually worked a little better, but because they're so big I actually got the job done this time (14 x 28 pool) for less than half what I paid at the pool shop. So yes, they wear out quickly, they all do. Apply light pressure and resist the temptation to use it "long ways". Use the short end or angle and target each Scale Crystal individually and they will go much further. Do not "scratch" as this will only cause rapid wear. Worked EXCELLENT for me.
