I've tried alot of things to try to remove the white from the black plastic on my punto evo, i always try to be careful while polishing but theres always the odd parts that get touched and usually a few minutes later there nice & white.

I've tried a few different things to try to remove it, and i just cant shift it.

Does anyone have suggestions to remove the white residue from black plastic?

I've used a scrubbing brush and a bucket of warm soapy water to fairly good effect - think it goes without saying to be careful of the paint lol

(T-cut on the plastic in my case, on my mk2 lol)

a pencil rubber gets it off

not as cheap as a pencil rubber but Autoglym Bumper Care removed the polish residue on my black trim. I'd tried a number of cheaper products which didn't work very well, this did remove the polish and also made the black bits look black again.

Clay bar and QD.

Peanut butter (non chunky).

i use panel prep solvent usually then treat with something like autoglym bumper care

There is a load of remedies out there. From bumper care as mentioned, WD40 even baby wipes, depending if the plastic is smooth or textured.

I tend to carry some wet wipes in the car for various reasons.
Silicone spray is another . Detailing wet wax, the stuff that can be used on just about any surface & doesn't go white is a handy thing as well. Especially if youre the type who cant keep to one surface. If you know what I mean.

Autoglym Bumper Care!

I second the smooth peanut butter.

Sounds a bit kooky but it does work and leaves a good shiny too.
