Fully agree there. Would be nice to get a PLA as well as a PETG smoothing solution that doesn't require a full hazmat suit and respirator just to be able to survive another day. ABS and Acetone are and have been common knowledge for quite a long time. However the only chemicals I know that would perform the same or similar process on PLA are extremely hazardous and very very inappropriate for home use. Not aware of any reasonably safe ones for PETG either.
