Web18 Feb 2016 · Re: My Experiences Reflowing Videocards (so far 100% success rate) The whole board gets dunked in a tank of an appropriate cleaning fluid in an ultrasonic cleaner. What happens after that depends on the cleaning fluid used, but may involve rinsing with deionised water and/or IPA then low temperature hot air drying.
