No other ice and snow melter works like Safe Paw - It is totally unique. Safe Paw is a patented dual-effect compound. The liquid component starts melting ice instantly while breaking its surface tension. This allows the crystal core to quickly penetrate and destabilize the ice and speed up the melting process.
