removing polish on black plastic

[Sidewaze Samm]

Hi
I was wondering if there's any detailing experts out there who can advise the best (that is, the easiest :roll: ) way to remove the white marks of 'overpolish' that are left on grained black plastic trim pieces.

My wife got her new black Mini two years ago. On collection, there were a couple of white marks on some black plastic trim pieces (wheel arch and indicator housing). Just the sort of mark that gets left when polish/t-cut is applied to the paintwork carelessly. The trim is a rough/grained finish so the marks won't just rub off.

To be fair, over the last two years I've not exactly tried very hard to get them off. In fact, not tried at all
But it's really starting to annoy me. Is it a case of scrubbing with an old toothbrush, or is there some magical, mystical solution that can be used?

cheers

Defo worth giving WD40 a try with the toothbrush. Actually WD40 looks great on most dark plastics. If you want something that doesn't enhance or gloss up the plastic at all then something like Bilt Hamber Surfex HD will work.

Need to be careful with solvents like white spirit as it tends to leave white powdery marks that might make it look worse. Petrol might be OK but I would test on a small inconspicuous area first.

Good advice above, but if that doesn't do the trick then get a heat gun, or decent hairdryer and heat up the plastic, it'll bring back the colour quickly.

Oh God, another 'Harley Wax' thread. This forum is costing me a fortune! :rofl:

I use Meguiars Gold Class Trim Detailer, there's a new one called Ultimate Black but I've not used it yet so no comment on it.

You really need to remove the wax/polish residue before treating the plastic with a trim dressing of any kind or it will reappear again when said dressing has worn/washed off. Isopropyl alcohol/rubbing alcohol usually does the trick for me.

thanks for that. Now, not intending to appear completely useless, but where's the best place to get some?

I bought some recently:

Once you've removed the marks with an alcohol, as noted above, I've got another trim product for you to try: Carspunk Exterior Trim Detailer. It's brilliant, and locally made. I just ordered a new batch as I ran out of my last bottle, and used it last night on the wing mirror surrounds to great effect.

I've used a few Carspunk (silly name !) products and been quite impressed with them particularly their Snowfoam. They're only 10 minutes from me in Leyland too. Will definitely be trying more from their range.

 

[tee.gilding]

I've found their exterior trim dressing to be top notch. Also some good smells. Not tried all that much of their range though.

a bit late now I know but it may help others. Just use a rubber/eraser. A simple, cheap, and effective tool!
