Methylated spirits or turpentine to clean resin printer?

Question

I'm new to 3D printing and have bought a resin printer.

Cleaning with Isopropol Alcohol seems to be the rage, however I think this is unaware of cost savings. It appears methylated spirits is ok and is 25% the cost of Isopropol Alcohol.

I'm now down to wondering if I should buy methylated spirits or turpentine (I ruled out kerosene as too flammable)? I'm leaning towards methylated spirits, however would like input.

Factors I'm curious about:

1. Cost: same for methylated spirits and turpentine.
2. Evaporation/solvency: ?
3. Flammability: ?
4. Poisonous levels: ?
5. Resin object cleaning effect: ?
6. Skin effects: ?
7. Smell: ?

I checked a few sources.

Answer 1

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.

Answer 2

Are you for real?

Isopropyl alcohol is less dangerous to your health than ethanol with a touch of denaturant?

Seriously read the MSDS sheets for the products and know what's in them before you say stuff.

The amount of MEK or MIBK is so small.

Some and not many methylated spirits have a small fraction of methanol but so little that it is safe to work with.

Why would they sell methylated spirits in the supermarket and not IPA if it was more dangerous?

Personally, I would read the SDS/MSDS sheet for the metho if you are worried and find one that is only denatured with Bitrex but to be honest I doubt there will be a health issue any more so than IPA with any of them.
