Unfortunately, I've gotten several acid stains on the polished wide stone slab in the window 
. What to do? Is there anything that can be done? Unfortunately, the slab cannot be removed and sent in for polishing. I'm desperate, can one sand it themselves?

If the surface has become uneven, it should be sanded down first, then polished. How this should be done depends on the type of stone; granite or marble have different properties. Ask where the slab was purchased. Some stone polishing uses water for cooling, so there might be some mess.
For marble, such a kit works. Don't know if something equivalent is sold in Sweden. http://www.amazon.com/FILA-RESTORAT...68917755&sr=1-1&keywords=fila+marble+restorer
