As an industrial and scientific buyer, I was hesitant to try another caulking smoother, but I was pleasantly surprised by these cleaning smoothers. They are efficient and easy to use, producing a smooth finish with little effort. As my tests showed they work well with all types of silicone caulking. The only con is that they are not very durable and can easily crack after several uses .Overall, i highly recommend these smoothers for anyone looking for a clean and professional finish..
