Black plastic bumper cleaning

["R. Tonge" <rptonge@u.washington.edu>]

Dear All

Anyone got any tips on how to clean black crinkly plastic bumpers.
Presently, they have a greyish finish to them - I think there is polish
and crud inbetween the ridges of the textured finish. I have tried a brush
and it wont shift it.

Thanks

Rob.
