    It came back with so many hits I couldn't work out what the active ingredient was. At least one of the products in the hits *does* attack Polypropylene. ...but yeah, if someone can tell me what's in it it could be perfect.

    Polypropylene is resistant to most organic solvents. Try WD40. It's pretty good at removing glue residue

    Thanks that's useful. Glycol Ether won't hurt it. Aliphatic Hydrocarbon might.

    Thanks, Google suggests Polypropylene is totally immune to WD-40. Will give that a go.

    6.2 Resistance to Chemicals

    Dilute Acid Very Good
    Dilute Alkalis Very Good
    Oils and Greases Moderate (Variable)
    Aliphatic Hydrocarbons Poor
    Aromatic Hydrocarbons Poor
    Halogenated Hydrocarbons Poor
    Alcohols Very Good

    ..and this:

    Looks like meths will be fine too.

    and this:

    Conclusion

    Meths won't hurt the polypropylene, but won't touch the tape either.

    So WD40 FTW. Won't harm the polypropylene will dissolve the tape. Thanks steve1963.

    The tables and charts you have been looking at are based on medium to long term exposures.

    None of the substances mentioned in this thread will have any noticeable effect on polypropylene in a few second or even minutes.

    Try what you have to hand. meths, white spirit etc etc but next time you are in a hardware shop or a DIY store buy yourself a bottle of Sticky Stuff Remover

    Automotive panel wipe is good stuff to have onboard. It's used for de-greasing paintwork prior to re-spraying and doesn't harm any of the plastics on cars, as far as i know. I've used it for many things on boats, removing masking tape and gaffer tape residue amongst them, including from acrylic panels when replacing the acrylic in hatches on my own boat.

    Thanks, I'll bear that in mind if the WD40 isn't very effective.

    Thanks all did the job last night. WD40 dissolved the tape glue and didn't dissolve the polypropylene. Still took a little bit of elbow grease...

    I've learned my lesson: Use gaffer tape wisely.
