Smell is a large part of it for me, but honestly what led me down this investigation was a YouTube video. A maker was testing out cleaning agents (Mr. Clean, Simple Green and Mean Green) to clean off resin prints (made on cheaper printers with Elgoo resin). He seemed to get better results for less money with the cleaning agents than IPA so I wanted to see if anyone had tried it with the Form Wash since I have one of those for my Form 3 which is on the way.
