Mr. Clean has a product called the 'Magic Eraser'.
It is a sponge made of a lightweight foam material.
You simply wet it and attack dirt with it.
I had not seen enthusiastic testimonials such as they garner,
other than with something like the Surfpick.
I tried it this morning.
First I tried a back door panel.
I just tried some Race Glaze on this a few days ago...
and it did not remove the yellowing from the vinyl.
A few wipes with the ME and it was gone.
I just cleaned a vertical strip, so that you could see the difference.
I then went to my grimiest area, which is the driver's door panel
and tried it on a portion of the inside handle.
They don't recommend it on some areas, such as car bodies...
but many of the testimonials were for removing things such as tar from a car.
Some users that do a lot of vehicles say that it works best on white cars, for some reason?
I know that this is technically a 'detailing' issue...
but I wanted to make sure that my diesel brethren saw this.
If you try it, please share your results.
