Quick tip:
Put the dirty part, and cleaning fluid of your choice, in a disposable container (Glad, old peanut butter jar, margarine tub, whatever) that fits easily within the cleaner, and couple to cleaner with plain water. For my bike parts, I borrow the services of our lab unit, and this method keeps it clean enough for general use. Note: have the fluid level of the container match that of the cleaner for proper coupling.
If your cleaner doesn't have a heater, just pre-heat the container full of cleaner in the nearest microwave, add dirty part, and hit "go".
