Best for mattress stain removal?

Question:I was just asked by someone to find on the internet, a product that will remove stains from a mattress, primarily sweat stains and urine stains.
I looked it up but I couldnt find a definitive one or one that I know would work. Also, I want to be able to buy it at a major store like Home Depot or Wal-Mart in CANADA.
Any suggesstions?

Oxy Clean should do it..
I bought a steam cleaner, it will get stains out of anything just like at cleaners...
I bought at Walmart...
