    I've looked around, but haven't found any clear information yet about washing white-detail parts... must be here somewhere!

    I received my first samples, all looks good with the shape... but the surface is sticky-tacky... I assume this is residue from the liquid photo-polymer. (Am I correct in assuming that this material is laser-hardened in a pool of liquid resin?)

    What is the best way to wash this sticky film off?
    Soapy water?
    Or something like mineral spirits/paint thinner?

    Thanks,
    Pat M

    I just rinsed mine in water rubbing off the residue by hand. Its almost like 'glue' isn't it?

    Soak the parts in either Ammonia or Caustic Soda solution for about half an hour. Once the surface film has dissolved the parts should look shiny.

    I've had good experience with 2% caustic soda in warm water (by volume if i remember correctly).
    Although there's a warning, very thin parts should be soaked for not more than 20minutes, and be checked quite frequently, since caustic soda is corrosive, and can end up eating through very thin parts. (Although never happened to me).
