I just bought roller skates last week. For the first time today, I skated in a rink (instead of outside). I changed the wheels to a harder wheel because I was told they would be better for rink skating.Now that I have my less firm rubber wheels off of my skates, I noticed that there is black stuff that comes off the metal part of the wheel and onto my hands when I touch the metal center of the wheels. What is this?
Same amount of time as weed. Same chemical- just condensed and bad-tasting.
The street department of the city of Baytown TX of course.
