Xante EnPress transfer belt cleaning off flaw

[WeberPrinting]

Transfer belt started repeating this random line through printing at only half the expected 200,000 life.
Anyone have an experience with cleaning Transfer Belts and what to use?
I saw some Youtube posts saying Denatured or Isopropyl Alcohol.
Got nowhere with supply support at Xante. They said probably buy a new one - not much help.

Also have a question about safe vacuum for toner - see people refer to a "toner vacuum"
stating that there is a possibility of fire from using a standard vacuum to remove any excess toner from parts of the machine.
Does anyone use such a vacuum and can you recommend a reasonable priced one for such use.

My tech gave me his old toner vacuum. It's this model: Buy Omega Supreme Plus HEPA Vacuum - Atrix

I'm not sure if it's a fire hazard, but toner is too fine for standard vacuum cleaners, and it'll just blow the toner out of the air filter and go everywhere.

Not sure what to use on the transfer belt though.
