I have similar complaint as other blogger. This product was used to clean my leather and dash. There was overspray on my speedometer lenses. I used on 2 cars. It claims it is safe on plastic. Despite 2 months of sending the product to them, pictures of damae, TW testing and back and forth they denied my claim. I used no other product to clean leather on my new car. Don't use this product. It is like using acid to clean your leather and obviously will damage your plastic. Again, Turtle Wax does not back up their products and surely they know the damage their products can cause. The one pic I have shown is the one with the least damage. My Lexus damage was considerable.
