I try out various resins and cleaners to see what comes out the clearest from a small sampling. Resins used: Voxelab Transparent, Siraya Tech Simple Clear, Monocure Crystal Clear Tuff, Nova3d Ultra Clear High Transparency, and Monocure Rapid Clear. Cleaners used: Isopropyl Alcohol, Ethanol, Monocure Resin Away, Mean Green, and Simple Green
See what combination will work for you.
