Sodium, Potassium, Rubidium, Cesium, and Francium. Actually, they don't just melt water, they are pretty explosive upon contact (the ones at the end more than the ones at the beginning).

There are 3 basic ways to "melt" ice, as follows:
1) Addition of chemicals which drops its freezing point (salt, for example)
2) Increasing temperature (heat)
3) In SOME cases, increasing pressure. This only works if the temperature of ice isn't too low to begin with.
Check phase diagram of ice, link below.

Magnesium. Where I'm from they spray a liquid with it in it on the road, and it works great. Salt only melts ice to around -5 Celsius, while magnesium melts to about -20 Celsius. Some fancy and more expensive brands of salt(or ice melter) have this in it.

:) You made me go out into our SUPER cold garage to find our bag and bottle of deicying products. Just for you, these are the chemicals that were listed on the various labels (besides NaCl):
Calcium magnesium acetate
Potassium Chloride
Methyl Alcohol
Propylene Glycol
But...we just throw down some sand for extra friction and let Mother Nature melt the rest.

When an ice cube stays in the freezer for so long the ice cube will shrink. It's cool.

warm water bottle, electric powered blanket (careful with that one), area heater (better careful with that one). fairly, making use of a frequently happening fan on the ice will slowly soften the ice.

Compression. This is why skates work.
