Pick up some of those yellow rubber gloves that come up past the wrist (like 2$ at Walmart). Ideally you want the water temp as hot as the system will pump out, which is kinda harsh on your body. The gloves make that a non-issue.
They have textured palms so you can use your hands to wipe it in the water rather than using a clean rag every soak.
And make sure you do it repeatedly until you stop seeing oil rise up (I've done as many as 10+ cycles @ 15-30 minutes a soak). Take your time and be patient. If you do it a couple times and think it's good to go, you'll be sorely mistaken.
You'll know when you did it right and enough times. Your first few shots will go through the nose.
