The small ultrasonic cleaners are fairly inexpensive from Harbor Freight. I bought mine on sale for $25.00. They are the perfect size for small parts. I found that straight Naptha, that I can buy by the gallon from Home Depot, does a fantistic job on every watch part if put into it. I also wash the hairspring assembly and balance cock in the ultrasonic cleaner with Naptha and then dip the assembly in laquer thinner (not paint thinner) to rinse off any residual oil from the Naptha. I lay the parts on paper towels to air dry.
