Interesting. SG is one of the recommended cleaners for SCUBA regulators

Interesting. When I was a commercial diver, we'd use Lysol in the
decompression chambers, and also as a spray to keep helmets from getting too
gamey. I hate the smell of that stuff to this day. Simple Green wasn't
around yet. I have worked on a lot of regulators and hats in my life.
Fairly delicate stuff, but not rocket surgery.

In the DSAT gas blender manual SG is one of the recommended pre-cleaners
for O2 cleaning components, with some more exotic cleaners indicated for
the final cleaning.
