A kitchen dish-washing machine would suit your needs. Just give it a 
good cold water rinse after the cycle is done (before it has dried). If 
you have a fan forced electric oven capable of 80C~90C temperature 
setting then throw it in there for 0.5 hours.
The mild alkalinity of machine dish-washer cleaners won't harm solder, 
copper or gold surfaces.
