Red Caboose Wheel/Frame Black Coating

Thanx Matt.   My standard procedure for 40 years has been to wash before painting a model.   But, first time I ever had the described situation.   Now I will have to save that toothbrush strictly for wheels and side frames.

Lou, assuming those were metal wheels, you are likely seeing leftover cutting oil and the dirt it attracts. 

Several years ago, I replaced some .110 wheels with new .088 on a Tangent tank car, and was surprised to find its rolling distance had decreased significantly. After some investigation I found the oil, cleaned the wheels and rolling performance returned. Since then, this has become a normal set up task for new or maintained cars. I’m certain paint sticks better as well.

I always use a mild dish detergent and soft bristle tooth brush to wash new rolling stock as part of the prep for weathering a car.   Upon completing the washing of the wheels and truck frames for two new Red Caboose 34' NWP stock cars, I noticed that the toothbrush bristle tips had turned black.   I have never seen that before.  Can anyone explain?  TIA.
