When shooting slugs, do you clean more often?

I have been shooting NSA 36.2gr ammo with the factory lube.
I have shot 1000's of rounds without cleaning my slug liner A .
I recently installed the new Superior Slug liner in my M3. I have only shot 300 or so rounds through it, but it still shoots the H&N 38gr Heavies great.
I have some of the new Javelin 40gr ammo on order.
I would imagine I should be able to shoot 1000's of those also without cleaning my barrel.
