Whoever here told me to use that, you are a God. It got the off my turbines and tires and really took the shizznahh off my white lettering. I have another method to add to the mix though. Worked perfectly!
Westley's bleach + (http://usera.imagecave.com/markyannone/IWGT/MagicEraser.jpg)
= MEGA WIN
The magic eraser effortlessly got the grime right off and also deteriorated right away, but did the job. I will try a heavy duty pad next time.
Anyway, turbines are more clean than ever now. I threw away all the other wheel cleaning .
Your welcome! Don't go to a heavier pad though, it will scratch the f&^# out of aluminum wheels.
*Update* used pretty much the same combo on my engine bay 22 year old crud came off no problem and now it looks pretty much brand new.
Westley's bleach kicks @$$
GM brand White wall cleaner works really well on raised white letters. Also eats bugs and dirt/grime off of your car.
castrol super clean, purple power,greased lightning will yeild you the same if not a better result. May keep it in mind next time you are at the parts store ;)
Anything to make the job easier is worth every penny~!
I used this new labeled bottle of simple green (says pro grade) on my tc wheels today and it really took some crud off.. Didn't hurt my hands either.
