hi, i have white plastic on my bike that has set in dirt stains that cant be simply wiped off. will "plastic renew" or some other product take it out? or should i just try to sand it? problem with sanding it is that i seem to sand "in" the grit off the paper..anyway,, i cant afford new plastic, mines not scratched, its just got set in stains.
