Snow clearing: snow sticks to snow shovel? Growing helps

In certain snow conditions, the snow likes to stick to the snow shovel, making it very difficult to clean. If it is a metal bucket, the problem can be solved very effectively: with the hot air blower or soldering torch, spread a very thin layer of candle wax on the surface. The room is then only half the work! For wood or plastic blades, floor wax could have the same effect. I have not tried it though.
