OHmygod!
Don't you know you could be in trouble with the government for doing that!
It's worse than removing the tags from your bed!
Don't you understand the federal government spent millions and millions of dollars and NHSTA did the same to come up with the perfect placement for the reflectors to keep you safe?
They have done this for years for Motorcycles and you're just simply flipping them in the trash, I can't believe it.
I'd just put it in the sun, put some windex or Denatured Alcohol on it and rub until its gone!
