    Default turpentine on plastic - help

    hi, this may not be the best place to ask my question but i thought i would giv it a shot and hopefully someone can help or at least direct me to somewhere else where someone can help. I used mineral turpentine on hard clear plastic (please dont ask what it was exactly) to clean it but then the areas i cleaned were foggy and full of wipe marks (it was nice and shiny before). Is there any way i can fix this? If so how and with what? Is the plastic actually ruined or is the turps just dried up it and only needs to be removed with something? Hope someone can help because this plastic thing is important for me and it will b very hard and expensive to replace.

    For what its worth. When I wash paint brushes in turps I finish with hot water and soap that seems to get a bit more of the residue out.

    Plastic polish such as Novus Plastic Polish should fix your problem. Buy the 3 pack and use as per directions.

    As far as I know, you can only get it on eBay:

    novus polish | eBay

    It's also great for acrylic and resin pen blanks

    I'd try the plastic polish, it can also be used to rescue scratched CDs.

    If you find a post of mine that is missing a pic that you'd like to see, let me know & I'll see if I can find a copy.

    What has happened is the Turps has melted the top 0.025mm of your plastic/ perspex,

    get some 2000# w&d rub down with this and water, , then using a sander polisher( NOT AN ANGLE GRINDER) ,CAREFULLY BUFF WITH AUTOMOTIVE PAINT CUTTING COMPOUND.

    Once you have a polished clear surface , you can polish again with AUTOSOL, BY HAND.

    you should then have no other drama's , do not use solvents on plastics.
