What, exactly, is a body polish? Is it like a massage with a scrub? Or something else altogether?

I have a gift card from my b-day for a local spa that does a 75 minute body polish—it's listed under their massage link but under a separate heading called "Body Treatments" on the massage page. They can't seriously scrub your ass for 75 minutes, right? This is part of a massage, isn't it? Or am I wrong? Has anyone done this before?
