Methylated spirits or turpentine to clean resin printer?
I would personally stick to isopropanol. Be aware that 3D printing is a very expensive hobby, but health wise this is a better option. Methylated spirits can quickly become dangerous, and often can burn with a close to invisible flame, meaning that you may not even see if it is burning. Also, the fumes can quickly become dangerous, whereas after years of dealing with isopropanol I have noticed no ill effects. Cost should not be your primary concern, health of you and your printer should be.
