You cannot avoid having oil in the gaiters when filling.
When I saw the rack was full by a kind of overflow, I had the rack move many
times by this assuring the oil has spread all over the rack.
I then checked for oil still present in the gaiter - it was not or just a
little.
I suppose this is the best effect to achieve leaving surplus oil from the
gaiters.
Cheers,
Hans

Now, just how do you keep the oil out of the gaiters?
