Does anyone on this list have any techniques for making mouth foley not
sound like mouth foley. For example, I'm trying to make a milk carton run
down a hallway and I need to come up with a sound for its footsteps. I've
got a pretty good mouth sound that I made, but it still sounds like I made
the sound with my mouth. Any ways of processing to disguise this?

You could try sharpening the attacks with some compression. Just set an
attack time of about 50-75 ms. A high-pass filter can help, too. Also try
some very short delay to give you a fixed flange sound that notches out some frequencies and changes the character of the sound. Lastly, use the mouth foley as a timing and feel reference while you build more realistic sounds in sync on a separate track (Basically, replace the mouth sounds with real ones but keep the timing and volumes the same).

Or  combine both elements together ... You could even use a envelope follower against your vocal for the milk inside & add some foley techniques....Experiment its the best success

Here's what I ended up doing:
I used the sweeping part of the mouth foley (for the carton brushing) but I
ran a high pass filter, compressed and did a sweeping pitch envelope to give
it a (forgive me) 'wacky edge'.  Then I replaced the impact clicks with
pitched up bubbles. It sounds very cute and cartoony like I had hoped for.
So, thanks for the suggestions, they were right in line with what worked.
I've got to look more into those envelope followers.

What is an envelope follower?

Charles Deenen
a device or plugin that "looks" at the envelope (how loud the waveform is)
of 1 waveform, and applies it to another. This is often used for filtering.
i.e.: the envelope follower looks at the envelope of the waveform and send
this to the filter cut-off (with some ADSR smoothing).

Paul Gorman:
Wave Mechanics Sound Blender has an envelope follower
with an optional sidechain....
