Horn switch was getting a bit intermittent,so I decided to clean it.I decided to use my $20 Aldi Ultrasonic jewellery cleaner I've had good results on fuel injectors and a flaky stop light switch.I filled the unit up to level with contact cleaner, in no way recommended.Worked a treat,I had cleaned the outside of the switch before cleaning.So I was surprised by what was in the bath.
