You need to use actual electronic cleaner in your ultrasonic cleaner (like Branson EC with DISTILLED water). I follow the treatment with a soak in 100% isopropyl alchohol to remove any residual moisture. Then dry it (i use a toaster oven heated to 212f . The most important part is using the correct solution in your cleaner. Alchohol is great for degreasing and flux clean up but won't fully dissolve any water corrosion or oxidation deep underneath SMD chips, etc.
