The carbon is NON conductive, thats why the switches stop working.
Wiping off the NON conductive carbon, allows the switch to contact.

BTW Pretty much all window switches do this wether they use a relay or not..

The grease used in Toyota switches become carbonized, and conductive.

Right ALL power window switches do this. So ONE incident triggers a recall costing millions which does NOTHING to improve safety.
