Below are pictures, this residue was beginning to accumulate inside the suitcase after a few uses. Just took a longer trip and think the wheels are finally worn in enough that the residue ruined two articles of clothing.
I tried to clean out the suitcase, but finally resorted to packing my clothing in plastic bags for the trip home...and again the build up was heavy when I unpacked.
It accumulates on the side where the wheel dust would kick up into the clothing compartment. Not sure of the model number but the sewn in tag is still in place.
