Removing ice cubes from the refrigerator only requires a plastic bottle.

3. Spray with warm salt water
Take a plastic bottle filled with warm salt water and sprinkle it evenly over the frosted surface. You'll then witness a magical sight: the warm salt water quickly penetrates the ice and begins to melt the frost.
The reason this is so magical is that salt water can lower the freezing point of ice, causing it to melt faster.
