Wahoo kickr Snap question

Is it possible to clean the role of the kickr snap? If so what can I use? My red Vittoria training tire has a dark dirttrack in the middle that is coming from the role. Can I clean this as well because it gives marks on the floor.

 

Thanks

Here is what Wahoo says about cleaning: https://support.wahoofitness.com/hc/en-us/articles/204937884-My-Tire-Is-Slipping-Squeaking-Or-Making-Noise-What-Can-I-Do-

 

I use rubbing alcohol to clean both the roller and the tire – every couple of weeks.

3000+ Zwift miles on my Snap and the roller is in pristine condition.
