There are some alternatives.
You can use chloroform to "etch" acrylic surface. Unlike other solvents chloroform leaves acrylic surface nice and shiny. Yes besides the use in Bond-esque plots where chloroform is used for kidnaps it is also used as an industrial solvent.
Or you can use solvent from a set for casting acrylyc parts (in some parts of the world sold under the name Dentacryl, or Dentakryl)
Or you can use very fine sandpaper to smooth the surface and a polishing paste to polish the surface. You can use toothpaste instead of polishing paste. It is not nearly as efective, but it works. You can buy polishing paste in the car-shop accessories (it is NOT a wax, like Turtle wax, but a polishing paste for thorough ... aehm ... restoration of the paint).
I often use the polishing method.
It is very, very easy to polish the acrylic glas (if the original lightwedge is made from acrylic glas). You can polish almost any kind of hard plastic.
