A few of my tshirt masks . cut them wrong so they didnt work quite as well. Friend used cleaner on his auto battery connectors. A week later couldnt start his car. I insisted it was the connectors. He tried taking them off, cleaning, reattaching. then paid to get solenoid replaced. Still no luck. Put in new $11 wire and it starts. Cleaner apparently "dissolved " old wiring.
