The only thing i think methylated spirit could/may affect is the plastic of the print head and/or cartridges. If it does not affect the plastic of the carts it should be fine as a 20% replacement. It evaporates quicker than isopropyl alcohol in most cases from my experience. Typically as you mention it contains methanol this should not affect anything as methanol when exposed to oxygen evaporates/burns into carbon dioxide and water, neither of which should harm things.
Other additives it can contain are... isopropyl alcohol, acetone, methyl ethyl ketone, methyl isobutyl ketone, and denatonium most of them i am not familiar with although acetone can melt/warp certain plastics. Again however i would imagine it is in such a small quantity and being mixed with 80-100% distilled water i imagine would nullify that worry.
Personally as you say i would not use it to flush a print head just in case of damage, but it may be worth a go on flushing a cartridge, especially one with a pigment sponge for cleaning. I imagine it would do quiet a good cleaning job. I may buy a £2 throw away non-oem PGI cart, drain the ink and give it a try on that just to get an idea of the results. (at least visually). Ive used it on electronics for years, and never had an issue, you can soak a microchip in the stuff and it will not kill it. other additives in it could maybe block a print head but i personally would not think it likely.
Well i learned something there i did not know. If that is the case i personally would not recommend even though it has also been used successfully dish soap or as we call it in the UK Fairy/Washing up liquid for print head cleaning. That can contain all types of perfume and sodiums/salt which left long term would cause corrosion and probably a clumpy/gooey substance all over your print head. Requiring even more time soaking in water just to get rid of the build up.The microelectronic chip that is used in a thermal printhead has no encapsulation that most integrated circuit chips are packaged with, so I would be carefull with your experience with cleaning of microchips...
