take some of the dustremover shit in the can, turn it upside down so the liquid comes out, and spray the whole area till its covered in frost
then take a blowdryer on high, and heat the area you just sprayed
if you cant find the dust remover in a can, some dry ice will work well, but wear some good gloves when you handle it.
When you are finished, toss the dry ice in a bucket of soapy water
