I've not found a good electronics swab yet, if you have a link or brand recommendation then please let me know. For surface stuff I use a lens wipe and soak it. But for getting INTO stuff, yeah toothbrush is my goto...but I don't know about a memory slot. This DIMM contacts in the Fuel look FLIMSY and even catching those on a toothbrush makes me nervous. Why did the need to make them so fragile, when a normal PC RAM slot has a much beefier contact!

I have access to a small and huge ultrasonic tank (size of a large bathtub) at work, but in reality it's only good for removing corrosion with mild organic acids, great for carburetors...not so much for electronics cleaning in general. The big issue is if you want to do electronics you NEED to have a sweep function to sweep frequencies for interaction. Most of the stuff on the market is single hertz and that actually doesn't clean as well as something that shifts up and down. Some corrosion responds better during frequency shift. You do see the function advertised sometimes.

But yes, that's why I don't tend to use cotton swabs on electronics...catches and tears more than it works.
