Hi guys, is there a self life for methanol? I have a 5gal jug here that has about 3 gals left but its been sitting for about 3 yrs now. Its in its original metal can closed in a corner of the garage with no sun contact but garage temps do get high in the summers and just noticed when it rains some water gets into that corner this the bottom of the can (on the outside) is showing some rust.

You think meth is still good? Or not worth the risk and just get a new can.

Thoughts? Anyway to actually test purity?

Thanks in advance
