If your ultimate goal is to remove the greases more quickly, I would recommend two things: 1. Warm the solution. Not too hot as the detergent can be destroyed by too much heat.. 2. Agitate the solution. Some type of stirring device or solution circulation device. I wondering if anyone has ever tried an 'Ultra-sonic" cleaner with detergent degreasing solutions. One possible drawback would be that the teeth might be cracked...but aren't most removed? (NOTE: don't use volatile solvents in an ultrasonic cleaner)... Follow Wolf's suggestion as to how much detergent. Remember, more is not always better when using a detergent. It needs the water to work..
