I've not encountered grease coming back out. It takes a really good
tug to suck it in there and you don't get the same level of airflow
when in normal use. The grease is fairly thick. After a bit of initial
vigorous pumping by hand to spread the grease any excess is ejected
and I've not seen any more come out. I've done it to the clear
cylinders and a little stays top and bottom with a little smeared over
the inside.
