Don't know about a HF cleaner, but I use a roaster filled with 50/50 Industrial Simple Green (which is purple in color) and water. A 30 minute bath cleans carbs very well.

You can buy Industrial Simple Green at Walmart and Home Depot.

Does your HF cleaner recommend or prohibit certain liquids?

EDIT: I re-read your post. You meant a parts cleaner, not an ultra sonic parts cleaner. My mistake.
