I’m looking for some advice on cleaning PLA off of parts (preferably without harsh, caustic chemicals.)
As I’ve worked building 3D printers, I’ve got some print heads that have piled up over time, and they’ve all been massively coated in PLA due to head crashes, spaghetti, or other reasons. Over the course of about 4 years I’ve amassed about 8-10 of these.
Is boiling these in water in order to remove all the burnt/gunked on PLA an option? Or is that only going to soften the PLA and not remove it? Is heated lye the only option here?
Am I going to have to resort to a small CNC and a flycutter to get these looking good again?
