Soapstone: Natural stone
Pros/cons:
Heat resistant
Stain resistant, but especially tough stains won't wash away
Holds up to chemicals
Hygienic
Expensive
More likely to dent than marble and granite
Can scratch and chip, though you can finely sand small scratches and coat with mineral oil
Less common than granite
Optional periodic application of mineral oil will darken the counter and enhance natural aging process
Higher maintenance if you oil it
How to clean and maintain soapstone:
Use mild soap and water
Can use Ajax or Comet as well
Optional mineral oil application to darken color: multiple times in first year, then darker color should become permanent (also can use beeswax and linseed mixture for same darkening effect)
If using mineral oil, avoid cleaners with harsh chemicals because they will undo the oil process
