Grit,
Try spray 9 products too. Simple Green was designed and initially made as a cleaner in Boeing labs. As was WD40, Pam cooking oil.....that was not ment to be a cooking oil spray. Did not work as a non-oil based lube.....
Joys of having a step father that worked their back in the day that had to design and manufacture things. Heard a few good stories. Most forgotten being late 50s vs when told as a teen.
