Shielded mains cords just move the noise to the
next open spot, which is the unshielded plastic
boxes, and unshielded ROMEX wiring used in most
USA houses.
Better would be to put one of the snap-on ferrite
suppressors on the cord close to the scope.
I have done this on most of my electrically noisy
equipment, and it has done a super job of knocking
down the noise.

One thing that I have not seen mentioned, although it may have
in the past, is using shielded mains cords to reduce noise. I have
these on things that use IEC cords.
