It is surprising how quickly clipper blades get hot during use and if your not careful they can become so hot that your horse starts objecting especially if you are clipping where the coat is already thin. Keeping the blades cool can be done using the traditioonal method of submerging the clipper blades in methalated spirit to clear the dirt and release the grease but that can be quite inconvenient and so using the Wahl Blade Ice spray means you can pop the spray in your pocket and use as and when needed because it cools, lubricates, and cleans to effectively prolong the life of your blades and protect against corrosion.
