In the end I could ride the bike once and spray it with chemicals or ride through a nasty puddle with lots of oil in it and contaminate the pads and rotor. It is not a time thing it is a single incident that can cause an issue. I got some mineral oil on a rotor that had very little time on it and tried to decontaminate and it didn't work so I had to replace it. It was hardly ridden but it got contaminated in one incident.
Sometimes alcohol, flame and sanding will do the trick and sometimes it won't.
