Winter flying with retractable gear?

This will be my first winter flying the club's Lance. One instructor told
me that you want to tap the brakes before retracting the gear to dislodge
any slush or snow so that it doesn't freeze in the wheel well, and I read
somebody else saying that you should hold off retracting the gear after
take-off for a little while to blow the slush and snow off. Should I do
one or the other or both?

I do both on the Arrow I fly.
Some will argue that leaving the gear down longer just freezed the slush
faster. To me the most important is to blow it out of the brakes.

My understanding is that you don't want the gear to freeze in the gear
well, so you leave it down after takeoff to ensure that anything that's
going to freeze will, and then if the gear is going to get stuck it's
stuck down, not up.

That's called fixed gear, down and welded.

I spent lots of hours in a Mooney in the northeast, winter and night, never
took special precautions with the gear when on an inch of snow or slush. I
don't remember a runway being sluch covered, but taxiways had been, and I'm
guessing the takeoff run was enough to remove whatever slush might have
accumulated. It may also be people who live in colder areas than Massachusetts
have to do things differently. There's nothing in the approved manual that
says anything about special care (that I remember, at least)

I was taught to tap the brakes to stop the wheels from spinning before tucking
them away. (spinning tires bulge out a bit, or so I was told) I confess I've
never actually looked down (sometimes I fly a cutlass) to see how long it takes
them to stop on their own.

I'm not sure how tapping the brakes dislodges any snow. There's very little
shoe travel.

At the rate it takes the Cessna single mains to retract, it's probably
stopped :-)

Correct, if you've got disks there's not much clearance there to begin
with. For other forms of brakes, it's not even going to do anything.

Of course all this stuff neglects the nose gear.

To me that sounds like a good way to have the brakes freeze.
I have never tapped the brakes yet. OTOH I did land with the brakes
locked one time. Interesting experience.

In the Deb it takes 10 to 12 seconds. POH says not to retract until a
safe altitude has been reached.

If they've been used the disks are warm to hot. tapping the brakes
could cause water to collect.

It doesn't have any brakes to freeze either.
