Open it up, take out the components and wash them with DISTILLED water. Do multiple washes/baths. Dry completely before turning back on. It won't fry your components because pure water is non-conductive. However, you risk galvanic corrosion of dissimilar metals if you turn it on before completely dry!!!
No need to use isopropyl, since the soda residue is completely water soluble.
Existing corrosion and fried chips won't be fixed by this.
