Does anyone have a good way of cleaning z scale loco wheels. I have just had 2 GP 38s arrived from weathering and the locos run poorly. I think the wheels need a good clean or they have some paint on them.

I use a Qtips and dip with alcohol, and wipe it around the wheels. For some of the really tough crud in the wheels, I scrape it off with a hobby knive.

The same thing happened to me after I weathered my PLE 38s. What I found is some of the dull coat had gotten onto the contacts on the truck and chassis. Clean the wheels, but also clean this contacts. I just used a little rubbing alcohol and a soft cloth to clean the contacts. I used Conductalube after I cleaned the contacts. The running drastically improved.

In my opinion the problem comes from traction tires. As they grip everything they are in contact with, one cannot do what is convenient with a MTL loco for example (as it has no traction tires): laying the loco on track, one truck laying on rails, the other truck on an alcohol soaked cloth and sending juice while holding the loco.
What I do my my own AZLs: putting them wheels up in their box using it as a crate, applying a 4.5 volt flat battery on an untired axle and cleaning every untired spinning wheel with an alcohol soaked brush.
But one has to keep in mind that tired wheels roughly act as if they were insulated, thus a 4-axle diesel roughly becomes a 3-axle diesel when speaking of power catching.
That's finally what makes me decide that my future layout and the AZLs that'll run on will be DCC.
