I was having a really rough time and my mom actually came up with this little trick, not sure if she read it somewhere or if she just smart, but here goes.
Slice the reflctor off using a strand of dental floss, holding kind of like you do your teeth and gently sawing away. Then soak in W-D-40, it will come clean as a whistle.
