Just keep playing with it. I guess from what people are saying they are really against water and that has changed my solution for sure.
I try to use as little water as I can , if possible none and will probably continue to never use it again.
So simplegreen straight im sure contains water itself....so im not sure what to really go with. Then the alcohol contains water as well.
Im thinking I might just go with the denatured alcohol from now on to be safe. I havent noticed any rust on my nitro. But I did just take apart my electric motor and finally found some rust way inside of the motor.
This might just happen though cause im in a humid environment. But It made me think. So just posting my happenings. Hopefully we will all find the correct mixture. But most likely its going to be personally pref.
Where as one guy wants a ton of simple green he will mix it 1:10 water. Getting himself a ton of liquid and lasting a long long time. While Ill probably stick with 1:1 ratios and zero water. Increasing cost and strength and hopefully keeping rust at bay.
Im going to do more research on simple green before I cut it out entirely. But I will continue to use it on my tires. Its far and away always going to be great with that. Removing all the dirt , dust from it.
I might use it on certain areas and then blast it off to degrease. But the nitty gritty will probably be the denatured.
I posted the iso 90% though for those who are going to continue to use that. Thats at least less water content and more strength and will always be the most non-toxic way to clean the car.
But I can deal with the fumes. I just dont want rust. But right now I havent found any except for that weird one. Granted this motor is also very old, so it probably didnt help things.
Hope this helps. Take care guys , been fun sharing the tips.
