That is basically what I did, hot water in the sink immediately afterward, and blow dry with heat gun. (Don't have compressed air)
I saw earlier you said you did 8 minutes at a time, and heat on. Do you know how the temp affects the results? My carbs clearly did not come out looking as fresh as the ones you posted. I am wondering if it's primarily the combination of different metals together in the bath that creates the white build up? if you look at the top right corner of my after photo you can see some white stuff on one of the silver parts.
also when you say 2:1 of 2.5:1, do you mean 2 simple green to 1 water?
