    They are second hand, so I don't know if they fall within the "new eco formulation" range.

    I meant the available DIY strippers are "eco"

    Thanks for the oxalic acid tip.

    I've dismantled G-Plan furniture before and while they're not solid
    wood they've got a very thick veneer over composite boards.
    So, I think they wont disintegrate under a vigorous stripping.

    Best approach is to find an area that is normally out of sight and
    experiment. Paint stripper, acetone or hot air gun might do something.
    However, if it's a 2-pack lacquer you'll need an appropriate stripper,
    or to sand.

    Sanding good. The new strippers will strip acrylics OK

    But hmm.

    Depends what the finish is?? Acetone will remove some stuff

    If its hard try using a scraper and then sand

    Skarsten scrapers used to be good, until replacement blades became

    If you've used sharp glass edges in the past, you'll know that some
    types of paint/varnish that have totally dried over years are brittle
    enough that they are easy to remove by scraping.

    Not sure if that applies to two-pack finish, or whether it needs heat to soften?

    Thanks for the details. I must start using AI more.

    Just use a search - Google usually being the "go to".
    You don't need to interact directly with the AI, although it's great fun
    to play with ChatGpt. Try going to chatgpt.com and typing: "create image

    "how to strip g-plan furniture" into it.

    I have done this: chemical strip on the varnish. Then bleaching: oxalic acid solution was not particularly effective. Laundry bleach (sodium hypochlorite) diluted and brushed on worked well. (This was on stained beech, YMMV.)

    I have also seen hydrogen peroxide and lye used -- mix and brush on; recipes on the internet. Or brush the lye on, let dry, then brush the h. peroxide on. Beware: the mix will release oxygen, burst sealed bottles, which would spray reactive fluid around.

    It's important to do all the bits the same at the same time. I used the wooden knobs as test pieces to see how the wood reacts, and later replaced them with nicer ones on the final piece.

    Let dry very well before further finishing... the wood gets pretty wet.
