Review on 🔨 Premium 2-Pack Elevate Essentials All Purpose Pumice Stone – Ultimate Foot Care Solution by Kamil Campbell

I have tried several different pumice stones to remove scale (calcium?) from my pool walls and the comments mentioning that they are too soft may not have been tried by others. a very soft stone and that's part of how it works. Removes scale without damaging the shotcrete 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 finished the job 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.
