    Hi all,

    I've read about using alcohol to remove paints.

    If the paints are painted on clear/transparent plastic, will using alcohol remove the paints and reveal the clear plastic "unharmed" (still look clear instead of looking frosted from the alcohol)?

    Thanks

    Yes it will leave the clear plastic clear....

    Test first with 70% alcohol!!...we have had accidents happen where the stronger stuff (91% and up) just destroys the clear plastic parts....

    But yeah, it will leave the plastic nice and clear....no frosting has ever occurred to any of the parts I have worked with.

    I use 99% Iso alcohol to strip my parts.
    I've had a few clear parts get wrecked, Cyb Excellion (doors & head), Ani Cyb Prime, Lockdown & BB (light Piping)
    I've found that leaving them just long enough (1 or 2hrs) to scrub the paint apps off, is the safest way (imo)

    I'm thinking of removing the paints on Universe 2.0 Prowl. The doors and some parts are made of clear plastics (i think). Hope it wont get 'destroy'

    No matter what don't use Acetone free Nail polish remover, I looked through someone else's "Help with paint removing" thread and they suggested using that cause it won't damage the plastic. It took a day or so but the plastic crumbled, including the whole brush I was using to wipe the paint off with.

    could only get 99.7% isopropyl alcohol.

    Should i let the part sit in the alcohol for 24hours? (read from tutorial)

    Can i dilute the alcohol with water?

    Thanks

    What about using something like pullys lift off? I have used it on plastic models with good results. I dont remember using it on clear pieces though.

    Well, this information wasn't included in the paint stripping tutorial I read, and I believe I just ruined 90% of the parts I wanted to use with 99%. These parts are gone, right? They won't...dry out or something and regain any strength, will they?

    Ancient thread - materials have changed a bit in the last few years, and 99% isn't a commonly found solution. Some of the newer clear plastics will crumble with any exposure to alcohol, even lightly wiping them vs a full bath. Others will haze or warp.

    It should be noted in any tutorial (if it isn't already) to test one part first any time you're trying something new, and to preferably test with parts that you can afford to ruin.

    I know the thread was ancient heh...
    I tried looking at the tutorials and couldn't find anything about why my parts were breaking. I did a search and this was the only thread that looked close.
    Is there a newer thread on this? I am working with one of those translucent DOTM exclusives from Target and trying to remove some of the paint apps. If any alcohol will ruin the parts, is there an alternative method of paint removal?
    Thanks!

    Edit / Clarification:
    I was using the 'try on one part' on one of the smaller parts. The paint cleaned off as mentioned in the tutorial. Everything seemed fine, so I dumped the rest of them in. It wasn't until I started cleaning off those parts that they started breaking.

    I don't think anyone has compiled a thread on the subject - I know I'm at the point where I just won't touch clear/translucent plastic with alcohol unless I can deal with it falling apart. I had a few cyberverse Dreadwings I experimented on, one crumbled after being submerged in alcohol. The second one I just used a q-tip dipped in alcohol, and the plastic soon cracked everywhere I touched it.

    In the past I've tried Purple Power to remove paint that alcohol wouldn't get rid of, but it is harsher on the plastic - it will most likely cloud anything clear and leave cloudy residue on anything transulcent. Dunking the pieces in Future afterward does help make some pieces clear again, but it's definitely going to be a case-by-case basis. I haven't seen if Purple Power or any other degreaser/cleaners works on parts that are known to dissolve in alcohol, I might have to try that out if I saved any of the ruined pieces.

    If there are any other ways to remove paint from clear plastic that doesn't involve them crumbling in alcohol, I'd love to hear them too.

    Take the following with a grain of sand:
    A friend of mine mentioned that a Mr. Clean Magic Eraser could remove some paint apps from GI Joes, so it might work for TF parts. I gave it a shot last night, and it *seems* to have worked.
    I first tried it on parts that I had already written off as gone, and when that seemed to work, I tried it on a small part that I hadn't already ruined.
    I still have to wait to see if cracking/fogging/etc happens later, but for now, it looks good. I haven't figured out how to use it to get the paint out of panel lines yet.

    EDIT:
    It seems like the surface isn't as smooth and shiny as it was before, but I am hoping a little polish will help. Definitely better than cracked or crumbling parts!
