I was told about this solution for cleaning glass, as an alternative to 91% ISO. And I must say it is much better and I believe cheaper. Its called Natures Orange Cleaner/Degreaser, I got it at Osh but I bet Home Depot or any hardware store should have it. Mine was 9.99$ for 3 litres but i bet it would be cheaper at bigger hardware stores.
It simply cleans vapor gunked up glass and even smoked glass much faster than ISO. I used to have to soak things it cleans just with shaking, not to mention it doesnt burn the hands and smells like Oranges to cover gross smells from cleaning. Its biodegradable and just seems the better alternative to ISO right now. I would recommend buying a jug, it will last many cleans and encourage you to clean your pieces more!
