Welcome Aleks. Yes, acetone will ruin the paint and or plastic if not a metal model. Often by just handling a plastic model without a cloth or soft gloves wears off the script. I searched the DLE-90 ingredients, but they aren't disclosed. Could be citrus based. It isn't expensive, and both Modelbahn shope Lippe in Detmold Germany and Trukmo have it and ship to the US. If the shipping is more than the product or equal, I would order other items with it. Both sell Herpa, Wiking, Busch, vehicles, scenery, and Structure kits as well as trains, motors, decoders, etc.
