Some of you have tried a number of ways to clean that oil looking puddle at the bottom of the intake. I remembered that I had a partial box of these swabs, courtesy of my spouse. It is rather easy to dab the bottom to suck up either that oil looking puddle or after using the cleaning fluids on the MAS or the throttle body itself; plenty long. Not sure where you can buy them, but doctors clinics uses them so maybe a drug store, Walgreens?
