No expierence needed !!! Just $7.00
I have used this method for removing the "fog" off the lens. It is on the outside as previously posted. It only takes 10 minutes a lens and almost makes them look brand new. I PROMISE THIS WORKS!! I have done it on friends cars, relatives cars, and other vehicles. It costs roughly $7 bucks to get it done.
New razor blade
Small bottle of wax cleaner
Electronic Buffing Machine
First, use a brand new razor blade held at a 90 degree angle to the lens and scrap off the ozidized stuff. Try getting as much as you can.
After completeing the razor blade step, then you need some wax cleaner (avaiable from local auto shops). You put a little on the lens and use a buffing machine to "buff" in the wax cleaner, making it clean again.
You save money this way as you don't have to purchase the new lens. If this does not work, I will personally bring my supplies and machine down to your house free of charge and do it myself.
