Compared to centerfire ammo, rimfire is dirty. It is a combination of dirty ignition primer, powder that is usual not fine grade stuff to say the least, bullet lube, lack of bullet jacketing, and gun designs that seem to trap crud in the action more readily than centerfire guns.
That said I hardly clean my .22s. Mainly because I don't depend on them for my safety, I shoot them more often than my centerfire guns, and they keep on going and ask for more no matter how I treat them. Gotta love em.
