Soak them for an hour? What, do you eat at your keyboard? I’ve had a Razer Huntsman Elite (with PBT upgrade set) for two years and only use canned air to blast out dust and random particles. I’ve removed all the keys and cleaned them once just using cotton swabs and soapy water.

No issues here. In fact, I’m working with them right now and they responded in a very timely manner. They’ve always been very helpful.
