Aluminum residue on silver polishing mops

I usually send my polishing work of aluminum and stainless steel
parts to a very good workshop. I would like to use the same place for
polishing of silver.

If they use the same mops as the aluminum and steel will this ruin
the silver? Can tiny parts of the metals get imbedded in the silver?

Thanks in advance
