Hi John, sorry to hear of your event. One of the more harmful things that could have been in your fire might have been PVC. That produces hydrogen chloride when it burns which reacts with atmospheric moisture to form hydrochloric acid which will obviously attack many materials. If you can identify or suspect burnt PVC, that could be worthy of giving that priority when cleaning up.

Re the ultrasonic cleaner, be aware that many of the fluids that are sold to go with them are alkaline and will attack aluminium and some other metals. I've even had corrosion problems with one 'neutral' cleaner used in a bath. Perhaps a mixture of distilled water with 10% IPA could be tried, but keep the temperature at no more than 30'C so the alcohol does not evaporate too quickly.
