When it comes to chrome I think they are actually easier to clean. The surface of chrome is so smooth and slippery that not much will ever really stick to it. I've had chrome wheels before on my last car and found it extremely easy to clean them because dirt would just slide off. You could take a dry paper towel to them and clean them with nothing else. I used regular 409 surface cleaner and NO wheel cleaner, because in the past, all those wheel cleaner's out there are way to harsh for any cars clear coat. The clear coat can come off on any wheel type if it is to acidic. So I have to say chrome may get dirty or appear dirty faster than regular wheels, but I think they are much easier to wipe off.
